SYNOPSIS Nutritional assessment has been considered as a cornerstone of nutritional diagnosis, management, intervention and dietary planning. Specific criteria, methods and procedures should be used for different age groups through a person‟s life cycle based on the requirements of each age group. Use of precise and accurate nutritional assessment tools and procedure to detect those who are malnourished or at risk of malnutrition will help dietitians to create an accurate dietary plan and intervention, which may help in quality of life improvement. This hand book includes the details of each assessment method for different age groups, from pregnancy to old age. It will be used as a quick, practical guide and reference for clinical dietitains. It includes dietary, anthropometric, biochemical and clinical assessments.
NEED FOR THE BOOK As a member of a medical team, a dietitian should put his/her input (i.e., a dietary plan) as a part of a comprehensive treatment plan, which is basically based on nutritional assessment. As each age group has specific methods, procedures, calculations and requirements, this book discusses in detail all the components of nutritional assessment for each group, to be easy, quick, direct and available for clinical dietitians in the field. This book includes the equations, tables, figures, and procedures for comparison with the normal references to be documented in patient records. Dietitians‟ communication with each other and healthcare providers will be through these documentations; in addition, this book will benefit nutrition and dietetics

Chapter 1
NUTRITIONAL ASSESSMENT DURING PREGNANCY INTRODUCTION Maternal nutrition has a critical role in the reduction of both maternal morbidity and mortality. The term Maternal Nutrition refers to nutritional status during any stage of a woman´s reproductive age that eventually could affect her health and that of the fetus and infant. There are heightened nutrient needs during pregnancy; without an increase in caloric and nutritional intake to meet the increased demands during this period, the fetus uses its own reserves making it more susceptible to pregnancy-related complications [1]. Women´s nutritional status is most vulnerable during pregnancy; maternal malnutrition becomes a cycle when malnourished mothers give birth to low birth weight infants who in turn become malnourished mothers themselves [2].
Basic nutritional evaluation tools during pregnancy will be detailed in this chapter, these must be used especially in high risk populations that include: Pregnant adolescents especially those out of wedlock [3, 4]. o Women with low prepregnancy weight. o Women with unfavorable prognostic factors e.g., Obesity and anemia. o Women with a history of low birth-weight infants. o Women who don‟t gain sufficient weight during their pregnancy.
2
Ghazi Daradkeh, M. Mohamed Essa and Nejib Guizani o o o
Women with a frequent history of conception. Women of low socioeconomic status. Women with diseases that can influence the nutritional status e.g., Allergy, diabetes, tuberculosis, drug addiction, and mental depression.
When nutritional assessment has been carried out successfully and high risk populations have been identified the next step would be to follow the recommendations detailed below: [5]
Recommendation 1: Preconception folic acid; folic acid is provided as supplements in addition to the adequate intake of high folic acid food sources. Recommendation 2: Proper antenatal care which ensures a proper weight gain during pregnancy. Recommendation 3: Iron and vitamin A supplementation during pregnancy. Recommendation 4: Nutritional counseling and education to ensure a healthy diet during both pregnancy and lactation. Recommendation 5: Breast feeding and nutritional education during emergencies.
The main forms of maternal malnutrition include [6, 7]:
Macronutrient deficiencies: (Protein Energy Malnutrition - PEM) which is managed by ensuring adequate variety of foods to include the 6 major groups, adequate frequency of food intake, adequate amounts of food, and proper personal and environmental hygiene. Micronutrient deficiencies: such as vitamin A deficiency (VAD), iron deficiency anemia (IDA), and iodine deficiency disorders (IDD); these conditions result in increased risk of low birth weight, maternal mortality, and neonatal and infant mortality. Anemia accounts for approximately 20% of maternal deaths as it increases the risk of both hemorrhage and prolonged labor, which can lead to sepsis. Management of micronutrient deficiency consists of supplementation with fortified foods and mineral/vitamin formulations, and adequate intake of foods rich in micronutrients such as fruits, dark-green and brightly colored vegetables.

Nutritional Assessment during Pregnancy
Dietitians play a vital role in the delivery of care to the patients; as an integral part of the health care team; providing patients with optimal care. Dietitians must have guidelines for giving legal aspects of documentation and avoid the pitfalls of improper investigation, assessment process, and documentation [8, 9]. Causes and consequences of maternal Malnutrition [6]: Causes and consequences of maternal Malnutrition [6]: Consequences:
Immediate causes:
Underlying Causes: o Inadequate maternal care. o Household food insecurity. o Unhealthy environment, insufficient health services, and poor hygiene and sanitation.
o Infections and diseases. o Poor access to basic health services (e.g. inadequate iron and folic acid supplementation) o Frequent parasites and infections. o Inadequate food intake due to diet characterized bylow, highly variable over seasons, and oftenlow nutrient density.
Basic Causes o Political structure o Resources and their control o Heavy workloads o Frequent births o Harmful local practices and food taboos. o Intra-household food distribution does not favor women.
Maternal Health o Increased risk of maternal death o Increased risk of infections. o Anemia o Compromised immune functions. o Lethargy and weakness. o Lower productivity.
Infant/child Health o Increased risk of fetal and neonatal death. o Intrauterine growth retardation, low birth weight, preterm birth. o Compromised immune functions. o Birth defects. o Cretinism and reduced IQ.

GOALS AND OBJECTIVES The main purpose of the maternal nutritional assessment is to support health care providers in the provision of maternal nutrition care and support services, it can also be used by health training institutions and other organizations, as well as other governing bodies implementing maternal nutrition interventions. These guidelines were established to break the intergeneration cycle of maternal malnutrition through outlining special nutritional aspects that enable optimal nutritional status of the mother as well as providing much safer and ideal birth outcomes. Furthermore, to improve the knowledge and skills necessary for the service providers at all levels to adequately respond to both maternal and infant nutritional needs; provide a basis for advocacy efforts which garner support for the maternal nutritional intervention at all levels. To contribute to the reduction of maternal malnutrition the implementation of the following goals must be achieved: [5, 6]:
To improve the knowledge and skills of service providers at all levels to respond to maternal and child nutritional needs. To improve provision of quality maternal and child nutritional services at community and health facility level. To advocate for support of appropriate interventions that address maternal nutrition at all levels. To facilitate health care providers and other stakeholders in interpersonal nutrition education and counseling, community dialogue, developing the health education for improved maternal nutrition. To strengthen integration of nutrition interventions for adolescent, pregnant, and lactating women within existing health services.
NUTRITIONAL ASSESSMENT FOR PREGNANCY Pregnant females who are in general at risk for nutritional problems at even greater risk, and because of the importance of nutrition in the course and outcome of pregnancy, all pregnant women should have a formal assessment

of their nutritional status at the beginning of their prenatal care with ongoing surveillance throughout the pregnancy [6]. The purpose of the nutrition assessment is to:
Evaluate the nutritional status of the pregnant. Identify those pregnant who are at nutritional risk. Formulate an individualized nutrition care plan with follow-up.
The Nutritional assessment takes into account different aspects: including relevant obstetric, medical, psychology and diet history, BMI along with weight gain, and lab tests and values.
1. Relevant History In order to have much more precise information; the following steps will help [10, 11].
Obstetric History Women with previous pregnancies may be at increased nutritional risk as a result of depleted nutrient reserves, the length and time between pregnancies can play a vital role as well especially if the time between pregnancies is less than one year. History of pre-term delivery (29

MUAC (Mid-Upper Arm Circumference) [13]:
MUAC is a good indicator of the protein reserves of a body, and a thinner arm reflects wasted lean mass, i.e., malnutrition. The WHO Collaborative Study 1995 showed MUAC cut-off values of < 21 to 23 cm as having significant risk for low birth weight (LBW).

DIETARY ASSESSMENT Dietary assessment includes: patient‟s food preferences, food allergies, food intolerance, eating patterns (meals and snack frequency, timing, location and food preparation). Dietary intake can be assessed retrospectively or prospectively depending on the purpose of the assessment. Day: Date: Meal type

NUTRIENT INTAKE ANALYSIS (NIA) NIA is a tool used to identify nutritional inadequacies before deficiencies are developed by intake monitoring. Direct observation or inventory of food eaten based on what remains on the individual‟s tray or plate is a method of actual intake evaluation. NIA should be recorded for 72 hours to reflect an average intake of an individual correctly.
FOOD DIARY Is a tool to assess food intake by documenting dietary intake as it occurs, usually for non-hospitalized patients. To estimate dietary intake accurately, the record should be on the same day and intake calculated and averaged for 3 to 7

ANTHROPOMETRY Anthropometric assessment is one of the components of nutritional assessment, it deals with physical measurement of individuals and relates them to standards for growth and development evaluation. The two most important measurements are weight and height. Unintentional weight loss is an indicator of serious disease [12]. Weight is important for energy expenditure estimation and in Quetelet‟s Index (BMI) [13]. Height is essential for quetelets index (QI), creatinine height index, and body surface area and energy expenditure calculations [14]. Body weight gain may indicate fat and/or lean tissue repletion, fluid retention or fluid overload as in edema, ascites, and pleural effusion; while weight loss may indicate presence of a disease or nutritional impairment.
72
Ghazi Daradkeh, M. Mohamed Essa and Nejib Guizani
Weight loss may result from use of diuretics which increase renal excretion, because of these changes body weight needs to be evaluated carefully. Weight may be evaluated by comparing it with desirable or reference weight, it can be expressed as a percent of desirable body weight as: % desirable body weight = current weight/desirable weight X 100 % DBW of ≤80% is considered as substandard [15]. 80% DBW means the patient is 20% below the desirable body weight. Nutritional status may be indicated by using recent body weight changes than the static weight measurement [16]. Changes in body weight can be assessed by calculation of percentage of usual weight by using the following equation: % Usual weight= current weight/usual weight x 100 Usual weight can be obtained by patient or his relatives or from patient medical record. Percent weight change is another approach to assess recent changes in body weight using the following formula [16, 17]: % Weight change = usual weight - current weight/usual weight * 100 Weight loss can be classified as in Box 2.

Adapted from Chumlea WC, Guo S, Roche AF, Steinbaugh ML.1988. Prediction of body weight for the no ambulatory elderly from anthropometry. Journal of the American dietetic association 88:564-568. *Age (in years) is rounded to the nearest year. **Weight is in kg: lb÷2.2 = kg, kg x 2.2 = lb, Knee Height is in cm: in. x 2.54 = cm, cm ÷ 2.54 = in.
Body weight change > 0.5 kg/day indicates an accumulation or loss of water and not loss or gain of fat or lean tissue, this means body fluid level changes is the main cause of rapid weight change. Metric measures such as subscapular skin fold, Knee height (KH), mid arm circumference and calf circumference can be used for ambulatory patient‟s weight estimation [18]. Table 2 summarizes the equations that can be used for weight estimation.

Patient age and the anthropometric measures that are available are the main determinants of which equation to use.
ESTIMATED WEIGHT FOR AMPUTATED BODY PARTS The patient‟s current weight can be adjusted to account for the weight of the amputated body part, if the patient has had an amputation. The following equation can be used to calculate adjusted body weight [15, 32]. Adjusted weight = Current weight/100 - % of amputation x 100 Table 3 shows the percent of total body weight contributed by amputated body parts of individual. Table 3.

Knee height measurement, Knee height was defined as the distance from the sole of the foot to the most anterior surface of the femoral condyles of the thigh (medial being more anterior), with the ankle and knee each flexed to a 90° angle. Teichtahl et al. BMC Musculoskeletal Disorders 2012 13:19 doi: 10.1186/1471-2474-13-19. Figure 7. Knee Height Measurements by Boardable Sliding Caliper.
Knee Height Knee height can be used for height estimation for patients who cannot stand or with skeletal deformities, severe arthritis paralysis and amputation [14, 18], knee height is the most common approach for height estimation because it has been shown to correlate highly with height [14, 19, 20]. The Quetelet‟s index (BMI) can be calculated and compared with various standards. Knee height measurement, using large, boardable sliding calipers [23] while the subject in the supine position (lying facing up) [14, 18, 21, 22].

MEASURING FRAME SIZE Frame size can be measured by several methods including the ratio of height to wrist circumference [34]. The frame size can be calculated by using the following formula, and classified as small, medium and large (Table 5). r = ht/c r: The ratio of body height to wrist circumference ht: Body height in (cm) c: Circumference of the right wrist in (cm).
WRIST CIRCUMFERENCE Wrist circumference is measured just distal to the styloid process at the wrist crease on the right arm using measurement tape (Figure 8). To measure the wrist circumference, the arm should be flexed at the elbow, and the hand muscles relaxed. The tape should be perpendicular to the long axis of the forearm. The tape should be touching the skin but not compressing the soft tissues, measurement is recorded to the nearest 0.1cm [35]. Table 5.

BODY FAT DISTRIBUTION Body fat distribution is an important concern of health implications of obesity [37-39]. Fat distribution within the body is more important than quantity of body fat, it can be classified in to two types: (1) upper body, or male type (android) and (2) lower body, or female type (gynoid) [38].

Case Study 3 Peter is 21 years old white man admitted to accident and emergency department because of car accident, he is unable to stand due to multi fractures, his weight 72 kg, and knee height was 51 cm, wrist circumference 22cm 1. Estimate his height. 2. Calculate his ideal body weight. 3. determine his frame size Numerous studies have shown that person with android obesity are at more risk for insulin resistance, hyper insulinemia, and pre - diabetes, type 2 diabetes mellitus, hypertension, hyperlipidemia and stroke as well as risk for death [38-39, 40 - 42]. Total abdominal fat or adipose tissue present in three regions: Subcutaneous (just under the skin), Visceral (surrounding the organs within the peritoneal cavity), and retroperitoneal (outside of and posterior to the peritoneal cavity). Total abdominal fat can be assessed by two approaches that are relatively easy to practice in clinical setting: Waist – to- hip ratio (WHR) and waist circumference WC is calculated by dividing the waist circumference by the hip (gluteal) circumference (Table 6). Height -Weight with relation to frame size for Persons Ages 25 to 59 Years can be predicted from reference Tables (Table 7).

Figure 10. Measurement of Arm Circumference.
WAIST CIRCUMFERENCE MEASUREMENT To measure waist circumference, locate the upper hipbone at the top of the right iliac crest, measuring tape is placed horizontal around the abdomen at the level of the iliac crest at fixed position, sung the tape but does not compress the skin, take the measurement at the end of normal expiration [39].
ARM MUSCLE CIRCUMFERENCE Arm Muscle Circumference (AMC) is estimated from Arm Circumference (AC) and Triceps Skin Fold Thickness (TSF) [18, 25, 26], it is accepted as measure of nutritional status as it is an indicator of muscle and subcutaneous adipose tissue. A non-stretchable measuring tape is placed around the arm, while the arm is relaxed, perpendicular to the long axis of the arm at the level of triceps skinfold site (Figure 10). Measurement must without compression of soft tissue and should be recorded to the nearest 0.1cm. Arm circumference can be measured in the supine position, either with the right or left side [18, 27]. AMC (cm) = AC (cm) - [π X TSF (cm)] [28]

ARM MUSCLE AREA (AMA) Arm muscle area is an important indicator of nutritional status and used as index of lean tissue or muscle in body [18, 28], Arm muscle area (AMA) is an estimation of the area of the bone and muscle portions of the upper arm [29], it is calculated from triceps skinfold measurement and the mid arm circumference. AMA is correlated with creatinine excretion in children [30], and with total body muscle mass in adult [24]. It can be calculated by the standard equation below. Table 8 shows the guidelines for interpretation of age/sex percentile values for arm muscle area [28]. Appendix 1 and Appendix 2 show mid – upper arm muscle area (cm²) by age for males and females respectively: AMA (cm)2 = [MAC (cm) – (π X TSF(cm))] 2/4 π AMA: arm muscle area in mm2, MAC: mid arm circumference in mm, and TSF: triceps skinfold thickness in mm.

Anthropometric standards for the assessment of growth and nutritional status. Ann Arbor: University of Michigan Press.
The Corrected Arm Muscle Area (CAMA) is an estimation of the area of the muscle portions of the upper arm, attempting to eliminate the area due to bone [29]. To correct the overestimation of AMA, Heymsfield and coworkers [24] developed the following revised equations by subtracting a constant that represent bone, nervous tissue, and vascular tissue in the upper arm: CAMA (cm)² for males = [MAC (cm) – (π X TSF(cm))]²/4 π] - 10 CAMA (cm)² for females = [MAC (cm) – (π X TSF(cm))]²/4 π] – 6.5

Where cAMA: corrected arm muscle area in cm², MAC: mid arm circumference in cm and TSF: triceps skinfold thickness in cm. The Mid-Upper Arm Fat Area (MUAFA) is an estimation of the area of the fat portions of the upper arm, and is simply the difference between the MUAA and the MUAMA [31]. MUAFA = MUAA - MUAMA Arm Fat Index (AFI), a percentage of the arm that is fat, using the following formula [31]. AFI = 100 X MUAFA/MUAA

NUTRITIONAL ASSESSMENT OF ELDERLY Nutrition care has a strong focus on disease prevention through healthy life styles in the elderly. Health promotion and disease prevention can be achieved by proper nutrition, independence, improving self-care behaviors and good quality of life education programs and strategies are necessary for elderly to teach them how to eat healthier, do exercise safely and stay motivated. Aging is a normal biologic process, organs change with age, some physiological functions may decline and they do differently between individuals and within organs. These changes can happen as a result of the aging process or as caused by chronic disease such as atherosclerosis. Body composition changes with age, fat mass and visceral fat increase, while lean muscle mass decreases. Loss of muscle mass, strength and function (sarcopenia) are age – related, which lead to alteration of metabolic rate, decrease mobilization and increase risk for falls and quality of life significantly affected [1]. As the number of older adults (65 years of age or older) is increasing worldwide rapidly, poor appetite, low food intake, low food variety among elderly people may expose them to risk of malnutrition [2]. Malnutrition is defined as an imbalance of energy, protein and other nutrient intake that may causes negative effect on body forms, function and clinical outcomes [3]. Malnutrition is more common in the older population. It is usually associated with impaired muscle function, decreased bone mass, impaired status, anemia, decrease cognitive function, immune dysfunction, poor and delayed wound healing, delay of post surgery recovery, increase hospital length of stay, increased hospital readmission rate, increase mortality

rate and increase cost [4]. Different age related changes in older ages cause reduce in appetite and energy intake has been termed as "anorexia of aging" (Figure 1) [5]. Early nutrition assessment of malnutrition or risk of malnutrition provide the opportunity to start early treatment and reduce the risk of morbidity and mortality, length of hospital stay and cost in this population [6].
MINI NUTRITIONAL ASSESSMENT (MNA) Mini nutritional assessment (MNA) was recommended by European Society of Parenteral and Enteral Nutrition (ESPEN) guidelines for detection of elderly people (>65 years) who are malnourished or at risk of malnutrition [7]. MNA is 18 – items questionnaire published by Guigoz et al. [8], it consist of 6 questions on food intake, weight loss, mobility, psychological stress or acute disease, presence of dementia or depression, and Body Mass Index (BMI). Alternate measurements such as calf circumference may be used when height and/or weight cannot be assessed for BMI calculation scoring. MNA categorizes the nutritional status of elderly into 3 – categories according to scores as: 12 – 14 are normal nutritional status, 8 – 11 indicate at risk of malnutrition, 0 – 7 indicate malnutrition. No laboratory data are needed for MNA (Figure 2).
ANTHROPOMETRIC MEASUREMENTS Calf Circumference (CC) Measure the largest part of the calf. You may need to search for the largest part of the calf by measuring above and below the middle of the calf, see Figure 11, Chapter 3.

MID – UPPER – ARM CIRCUMFERENCE Arm muscle circumference (AMC) is estimated from arm circumference (AC) and Triceps Skin Fold Thickness (TSF) [9, 10, and 11]; it is accepted as measure of nutritional status as it is an indicator of muscle and subcutaneous adipose tissue. A non-stretchable measuring tape is placed around the arm, while the arm is relaxed, perpendicular to the long axis of the arm at the level of triceps skinfold site (see Figure 10, chapter 3). Measurement must without compression of soft tissue and should be recorded to the nearest 0.1cm. Arm circumference can be measured in the supine position, either with the right or left side [9, 12]. AMC (cm) = AC (cm) - [π X TSF (cm)] [13]
HEIGHT ESTIMATION 1. Knee Height Knee height can be used for height estimation for patients who cannot stand or with skeletal deformities, severe arthritis paralysis and amputation [9, 14], knee height is the most common approach for height estimation because it has been shown to correlate highly with height [14, 15, 16] (see Figures 6 and 7 in chapter 3). Table 1 shows height estimation by using knee height. The Quetelet‟s index (BMI) can be calculated and compared with various standards (Table 2).
2. Demi Span Demi span is the distance from the midline at the sternal notch to the web between the middle and ring fingers along outstretched arm (Figure 3). Height is then calculated from a standard formula. 1. Locate and mark the midpoint of the sterna notch with the pen. 2. Ask the patient to place the left arm in a horizontal position. 3. Check that the patient‟s arm is horizontal and in line with shoulders.

4. Ulna Length (UL) Ulna length is the distance between the point of the elbow and the midpoint of the prominent bone of the wrist (Figure 5). This value is then compared with a standardized height conversion chart (Table 3). Arm should be bended (left side if possible), palm across chest, fingers pointing to opposite shoulder, measure the length in centimeters (cm) to the nearest 0.5 cm between the point of the elbow (olecranon) and the mid-point of the prominent bone of the wrist (styloid process) [19].

ulna. The skinfold site should be marked along the posterior mid line of the upper arm. Measurer should be stand behind the subject; skin grasped with the thumb & index finger of the left hand about 1 cm to the skin fold site. Caliper is about 1 cm from the left thumb & forefingers, caliper is perpendicular to the long axis of the skin fold, and the dial can be easily read see Figure 17 A in chapter 2. Appendix 1 and 2 show the reference values of triceps for males and females 20 years of age and older respectively. Ritz et al. (2004) [20] showed that knee height is accurately sufficient for height estimation in French elderly patients. Estimated height by using knee height and age was calculated by chulmea et al. [21] by the following equation. For men: height (cm) = [2.02 x KH (cm)] - [0.04 x Age (y)] + 64.19
(1)
For women: height (cm) = [1.83 x KH (cm)] - [0.24 x Age (y)] + 84.88 (2) Ideal weight for elderly people can be calculated by using Lorentz equations (WLO) (22) as follows: For men: H – 100 - [(H – 150)/4]
(3)
For women: H – 100 - [(H – 150)/2.5]

Body Mass Index can be calculated as: BMI = weight (kg)/height (m²) Sub scapular site is 1 cm below the interior border of the scapula, by gentle feeling for the inferior angle of the scapula or by placing the subject right arm behind the back while subject standing with relaxed arms to sides Appendix 3 shows the reference values of sub scapular for females 20 years and.

GERIATRIC NUTRITIONAL RISK INDEX (GNRI) Geriatric nutritional risk index is a new index for predicting the risk of nutrition – related complications. It can be assessed through the equation of Bouillanne et al. [22]. GNRI = [(1.489 X albumin (g/l)] + [41.7 x (weight/Wlo)] GNRI is defined four grades of nutrition – related risk (Table 3). Weight loss of 5% or 10% and albumin concentration of 38, 35, and 30 g/l were used for determination of GNRI.
CLINICAL ASSESSMENT Clinical signs can develop as a result of nutritional deficiencies; each clinical sign is related to a specific nutrient deficiency. Table 4 summarizes the clinical signs and nutritional deficiencies. The assessment of biological and social determinants of nutritional problems for elderly has been developed by using the DETERMINE checklist which focuses on Disease, Eating problems, Tooth loss and swallowing difficulties, Economic hardship, Reduced social contact, Multiple medications, Involuntary weight loss or gain, Need for assistance in self – care, and Elders at a very advanced age (Table 5) [23].
HYDRATION Hydration is the most common cause of fluid imbalance in older people. Poor hydration is clinically important because inadequate hydration is associated with many adverse consequences including poor oral health, poor skin integrity, constipation, urinary tract infection and confusion. Poor hydration itself can also contribute to reduced food intake and malnutrition. Dehydration, is a well known nutritional problem, can be defined as depletion in total body water content due to pathologic fluid losses, diminished fluid intake, or combination of both, institutionalized elderly patients are most particularly at risk of dehydration related danger [24]. Due to age related

changes in total body water, renal concentrating ability, decrease thirst, and medication relate hypodypsia [25, 26], confusion, disorientation, weak spells, infection, coronary artery disease, impaired or delayed wound healing, and death are dangerous side effect of dehydration [27-32]. There are different forms of dehydration (Table 6). Table 5. Determine Your Nutritional Health (23) The warning signs of poor nutritional health are often overlooked. Use this checklist to find out if you or someone you know is at risk. Read the statements below. Circle the number in the yes column for those that apply to you or someone you know. For each yes answer, score the number in the box. Total your nutritional score. YES I have an illness or condition that made me change the kind and/or amount 2 of food I eat.

Dehydration form Hypertonic dehydration
hypotonic dehydration
Isotonic dehydration
Definition is depletion in total body water (TBW) owing to pathologic fluid losses, diminished water intake, or a combination of both [29–33] a fluid depletion in which more sodium than water is lost and extracellular fluid becomes depleted [29, 31–34] a balanced depletion of both water and sodium, also leads to a loss of extracellular fluid.
Table 7. Assessment of hydration status Hydration status Dehydration Intravascular volume depletion hypovolemia
Criteria Serum osmolarity > 295miliosmolls a BUN(Blood Urea Nitrogen)-creatinine ratio above 20 or a level of serum sodium above 145 mg per deciliter a serum osmolarity above 295 milliosmols and a BUNcreatinine ratio above 20 [30].
ASSESSMENT OF HYDRATION STATUS Hydration status should be assessed at time of admission, as part of comprehensive. Physical assessment, and as deemed appropriate when acute situations occur [35]. Assessment of hydration status includes: a. Urine specific gravity b. Urine color c. serum osmolarity d. BUN: creatinine ratio
a. Urine Specific Gravity (USG) Testing USG has been shown to be a reliable and an important indicator of the body absolute hydration status [36] that can be used as a single measure, which is non-invasive, easy and quick to conduct in the field work [37].

Australian Pathology Association criteria defined a dehydrated state as a USG > 1.030. USG < 1.020 was the recommended cut-off point for euhydration by Armstrong et al. [38] and Shirreffs and Maughan [39]. Based on USG, hydration status were categories as Table 8 [40]. Table 8. Hydration status according to urine specific gravity Urine Specific Gravity (USG) ≤ 1.015 1.016–1.020 1.021–1.025 1.026–1.030 > 1.030
Hydration Status Optimal (euhydrated). marginally adequate hydration hypohydrated. severely hypohydrated clinically dehydrated state
b. Urine Color Urine color has also been used with reasonable accuracy when laboratory analysis is not available or when a quick estimate of hydration is necessary. Some data indicate that urine color is as good indicator of hydration as plasma or urine osmolality or urine specific gravity [41]. Good hydration can be detected when urine is plentiful, odorless and pale in color. Dark, strong-smelling urine could be a sign of dehydration. Certain foods, medications and vitamin supplements may cause the color of urine to change even though you are hydrated. Note: Use of a urine color chart is suggested for people with adequate renal function and not by people who wear incontinence pads.
c. Serum Osmolarity A common simplified formula for serum osmolarityis: Calculated osmolarity = 2 x serum sodium + serum glucose + serum urea (all in mmol/L) [43].

Osmolality can also be measure by an osmometer. The difference between the calculated value and measured value is known as the osmoticgap. Serum osmolality: 282 - 295 mOsm/kg water; a serum osmolality of 285 mOsm usually correlates with a urine specific gravity of 1.0 Osmolality may be affected by different conditions (Table 9). For serum osmolality values of less than 240 mOsm or greater than 321 mOsm are considered to be risky. A serum osmolality of 384 mOsm produces stupor. If the serum osmolality rises over 400 mOsm, the patient may have grand mal seizures. Values greater than 420 mOsm are fatal. When the serum osmolality is normal or increased, the kidneys are conserving water. As the serum osmolality rises, the urine osmolality should also rise.
d. BUN: Creatinine Ratio Elevated blood urea nitrogen (BUN) level with a normal or low serum creatinine level, may indicate under – hydration. A BUN: creatinine ratio greater than 20:1 is a sign of dehydration [45]. Dehydration is the loss of body water with or without salt, at a rate greater than the body can replace it [46]. Dehydration is common in the elderly and can lead to constipation, increased risk of infections, and medication toxicity. Risk factors for dehydration [47] as well as for over hydration [48] are summarized in Table 10. Each person considered at risk for over hydration or under hydration should have an individualized goal for daily fluid intake determined by a documented standard for daily fluid intake [47, 49]. The daily fluid intake can be calculated as follows: A. 100 mL/kg for first 10 kg weight B. 50 mL/kg for next 10 kg weight C. 15 mL/kg of remaining kg weight For people receiving a diet consisting of food and fluids: The number calculated for the standard fluid intake represents fluids from all sources (Food plus liquids).

a.
Up to seventy-five percent (75%) of total body fluids are consumed from liquids [33]. b. Therefore, total daily fluid intake needs to be multiplied by 0.75 to determine amount needed from liquids alone. c. Figure 7 provides an example of how to calculate required fluid intake needs from fluids alone when a person is on a diet of foods and fluids. For people receiving entire diet from tube feedings alone: As a general rule: A. 1 calorie/mL formulas are approximately 80%-85% water (e.g., 800 - 850 mL water per 1000 mL formula). B. 1.5 calorie/mL formulas are approximately 75%-80% water (e.g, 750 - 800 mL water per 1000 mL formula). C. 2.0 calorie/mL formulas are approximately 70%-75% water (e.g., 700-750 mL water per 1000 mL formula).
