Pedia II MALNUTRITION AND VITAMIN DEFICIENCIES - Dra. Anchores MALNUTRITION AND VITAMIN DEFICIENCIES Basic Assumptions: - Deficiency state seldom occurs alone - Anatomic lesion is an indicator of chronic nutritional disorder - Children are more vulnerable to nutritional insults Type of Nutrients: 1. Macronutrients – needed in large amounts and primarily function as sources of energy. (Carbohydrates, Fats, Proteins) 2. Micronutrients – needed in minute amounts and function mainly as cofactors in many chemical processes. (Vitamins, Minerals, Trace elements) Food Security: - Access by all people at all times to SUFFICIENT foods in terms of quality, quantity, and diversity for an active and healthy life without risk of loss of such access. - 3 dimensions:  Availability –supply of food  Access – household level reflecting purchasing power as well as transfer program; food shared equally within the household  Utilization – reflect the fact that even when the household has access to food, it does not necessarily achieve nutritional security Food Insecurity: - Limited or uncertain availability of nutritionally adequate and safe foods - Due to lack of resources to assure adequate production, importation and distribution of food

-

May lead to anxiety that food may soon become inadequate - More prevalent in developing countries (18%) - Tx: make the mother complete a 35day food diary appropriate dietary advice and or supplement nutritional counseling Hunger - The uneasy sensation that results from lack of food - Difficult to define bec concepts differ from each individual - USA: 8% of poor children +2 (obese) -

Etiology:  excess intake of food, exceeds expenditure  genetic constitution  gender  psychological, metabolic or endocrine disturbances  abundance of food in the Western society  decrease opportunities for energy expenditure due to sub-urban living Manifestaions:  most frequent: 1st year of life 5-6 years of life (gain appetite)

Pedia II MALNUTRITION AND VITAMIN DEFICIENCIES - Dra. Anchores Adolescence (gain appetite) small mouth and nose, doublechin  adiposity in mammary regions  pendulous abdomen with white or purple striae  disproportionately small external genitalia (boys)  Tall stature, advanced bone age, early puberty  Acanthosis nigricans ( hypertrophic hyperpigmentation of the skin commonly seen on the posterior neck and in skin creases) à seen at the back of the neck; reduce the weight and that will disappear Laboratory Findings: Those that evaluate CVS disease risks and diabetes risk (Plasma lipid profiles, FBS insulin levels, HbA1c), test for sleep apnea Prevention:  breastfeeding (look lighter and thinner than those infants in milk or formula fed)  delay in introduction of solid foods (increase sugar in milk formula)  counseling mothers to give food only in response to hunger not as a pacifier  reorientation of family life towards low calorie food  promotion of physical exercise Treatment: 1. Diet therapy - caloric requirement depends on age and gender - energy balance should be emphasized 2. Exercise therapy - schools should provide special programs - brisk walk (250 cal/hr) 

- regular physical exercise at school and at home should be planned - limit and monitor TV viewing time 3. Psychological therapy ( with severe or extreme obesity; requires certain intervention for their apnea) - emotional support - parental counseling - psychiatric referral “hard core group” 4. Other forms of therapy - fasting - intestinal by-pass operation - gastric stapling (hazardous, should not be advocated) Pickwickian Syndrome rare complication severe cardiorespiratory distress with hypoventilation CM: polycythemia o hypoxemia o cyanosis o somnolence weight reduction is extremely important TABLE 44-6 -- Anticipatory Guidance: Establishing Healthy Eating Habits in Children Do not punish a child during mealtimes with regard to eating. The emotional atmosphere of a meal is very important. Interactions during meals should be pleasant and happy.

Do not use foods as rewards. Parents, siblings, and peers should model healthy eating, tasting new foods, and eating a well-balanced meal. Children should be exposed to a wide range of foods, tastes, and textures. Foods should be offered multiple times. Repeated exposure to initially disliked foods will break down resistance. Offering a range of foods with low energy density helps children balance energy intake.

Restricting access to foods will increase rather than decrease a child's preference for that food. Forcing a child to eat a certain food will decrease his or her preference for that food. Children's wariness of new foods is normal and should be expected. Children tend to be more aware of satiety than adults, so allow children to respond to satiety, and let that dictate servings. Do not force children to “clean their plate”. Adapted from Benton D: Role of parents in the determination of food preferences of children and the development of obesity.

Nutritional Assessment - Primary step in the evaluation of children whose growth differs from the norm - Essential in the management of children with acute or chronic disease Methods of Assessment a. Assessment by history b. Clinical assessment c. Use of Growth Charts d. Anthropometric Indicators e. Laboratory assessment  Assessment by history - medical history - dietary history (mother’s, child) - weight and height changes - change in psychic reaction  Clinical Assessment - careful examination - observation - evidence of specific deficiencies  Use of growth charts - Growth charts are derived from longitudinal studies of a selected well-defined healthy population and from cross-sectional data on large numbers of children who participated in national surveys Data are presented as Percentile - Serial measurements are easier to interpret than single measurements  Anthropometric Indicators - weight - length - triceps skinfold thickness - head circumference - mid-upper arm circumference (MUAC)
