Morbidity and the growth of stunted and nonstunted children, and the effect of supplementation.

Children aged 9-24 mo were recruited by a survey of poor areas of Kingston, Jamaica. Stunted children were randomly assigned to supplementation or not. Weekly morbidity histories were taken for 2 y. Separate multiple regressions on each symptom for weight or length gain in 2-mo intervals showed significant reductions in weight gain with coughing, apathy, anorexia, diarrhea, and fever, ranging from -2.1 to -16.8 g/d ill. Apathy and diarrhea reduced gains in length (-0.26 and -0.20 mm/d ill). Significant reductions in linear growth with lower respiratory-tract infections (-0.16 mm/d ill) occurred only in nonsupplemented children. Growth over 4-mo intervals was reduced if diarrhea occurred in the first 2 mo of the interval but there were no long-term effects of apathy, fever, or anorexia. Some of the effects of morbidity on growth were therefore transient and morbidity is unlikely to be a major cause of growth retardation in this population.     

The interactive effects of dietary quality on the growth and attained size of young Mexican children.

Predictors of attained size at 30 mo and growth rate between 18 and 30 mo (eg, diet, maternal size, morbidity, age at weaning, and selected environmental factors) were investigated by using longitudinal data from 67 Mexican children aged 18-30 mo. These children were small because of growth stunting in early infancy. Between 18 and 30 mo they grew on average at the 50th percentile of National Center for Health Statistics references values for weight, and the 25th for length. Size at 30 mo and growth rates were unrelated to energy or protein intakes during the previous year, but positively related to consumption of animal-origin foods. Maternal weight predicted size and growth only for children with larger intakes of animal products. Individual rates of weight and length growth were uncorrelated on average, correlated negatively when animal-product intake was low, and positively only when more animal products were consumed. Integrated weight and length growth, and the influence of maternal size on growth, may be disrupted by poor dietary quality. Different children would be identified as malnourished depending on whether weight or length growth was measured.     

Growth trajectories are influenced by breast-feeding and infant health in an afro-colombian community

We conducted a longitudinal study among an Afro-Colombian population to investigate the influence of feeding practices and child morbidity on linear and ponderal growth during infancy. We enrolled 133 children at 5-7 mo and followed them until 18 mo. Repeated anthropometric measures were taken every 2-3 mo, with monthly interviews on feeding practices and daily self-reports on morbid conditions by the mothers of the infants. Mothers' social conditions and infants' fixed variables (gender and gestational age at birth) were measured at baseline. Growth starting points and trajectories were modeled via Hierarchical Linear Models (HLM). Children started with a mean length of 64.8 cm (95% CI: 59.8-69.7) and a mean weight of 7.68 kg (95% CI: 5.37-9.9), and gained length at a rate of 1.13-1.70 cm/mo, and weight at 66.5-319 g/mo. Breast-feeding, defined as receiving breast milk at any time within a 2-3-mo interval, was positively related to length gain (regression coefficient = 0.27 cm/mo; P = 0.04), after adjusting for social conditions and food consumption. Among mothers with low levels of education, breast-feeding had a positive effect on weight gain (regression coefficient = 0.30 kg/mo; P = 0.04); among nonbreast-fed infants, complementary food diversity generated a positive effect on weight (regression coefficient = 0.14 kg/mo; P = 0.03). Mean differences in length were related to the total proportion of healthy time (regression coefficient = 3.1; P = 0.02), whereas weight-gain rates were negatively associated with changes during illness (regression coefficient = -0.70; P = 0.04 for fever). No association was found between diarrhea episodes and infant growth. Our study confirms that breast-feeding after 6 mo of life is important for nutrition and health, likely by mitigating the negative effects of poor social conditions and diarrhea on infant growth.     

An energy-dense complementary food is associated with a modest increase in weight gain when compared with a fortified porridge in Malawian children aged 6-18 months

Poor complementary feeding practices are associated with stunting and growth faltering throughout the developing world. The objective was to compare the effect of using peanut-/soy-based fortified spread (FS) and corn porridge fortified with fish powder (FP) as complementary foods on growth in rural Malawian children. A total of 240 children were enrolled at the age of 6 mo and randomized to receive FS or FP. Both complementary foods provided 836 kJ/d from 6 to 9 mo of age and 1254 kJ/d from 9 to 18 mo of age. Children were followed monthly for anthropometry and fortnightly for the symptoms of fever, cough, or diarrhea until they were 18 mo old. Zn and Se status were assessed at 6 and 12 mo. The primary outcomes were the rates of weight and length gain from 6-12 mo and from 12-18 mo. Children who received FS gained 110 g more (95% CI 220 to 10) from 6-12 mo of age than children receiving FP. Weight gain did not differ between children receiving FS and FP between 12 and 18 mo of age, nor did statural growth from 6 to 12 mo or 12 to 18 mo. A total of 23% of all children were Zn deficient at 6 mo of age and this increased to 37% at 12 mo of age. Neither FS nor FP was associated with significantly improved Zn status. FS was associated with better weight gain from 6-12 mo of age and may be useful in conjunction with additional interventions to improve infant growth in the developing world.     

Growth faltering is prevented by breast-feeding in underprivileged infants from Mexico City

This study was designed to test whether breast-feeding protects infants reared in unfavorable environments from growth-stunting by averting acute infections. The body weight and length, feeding mode and morbidity of 170 healthy infants were assessed at 15-d intervals from birth to 6 mo. Birth weight and length were not different between groups, but at 6 mo, breast-fed infants were heavier and tended to be taller (P = 0.1) than infants fed formula. Relative to NCHS values, infants had lower mean birth weights than a sample of American and European BF infants. At 6 mo, the weight of BF infants caught up to the weight of NCHS standards, while infants fed formula fell to around -1 NCHS-Z-score for weight and length. The cumulative 6-mo weight increments were negatively related to the number of episodes of diarrhea, and positively to duration of lactation (P = 0.03, R(2) = 0.17). The 6-mo length gain was negatively related to infections but not to duration of lactation (P = 0.004, R(2) = 0.19). Never-ill infants attained a better weight (P = 0.04) and length (P = 0.02) than infants who suffered one or more episodes of diarrhea. Weight and length gain of infants suffering at least one episode of diarrhea was positively related to breast-feeding and socioeconomic status. Weight increments of 15-d were positively related to breast-feeding and negatively to the introduction of solids. In conclusion, breast-feeding positively affected the growth performance of the recipient infants by averting infections and possibly by improving nutrient intake during infections.     

Energy balance and the accuracy of reported energy intake in preadolescent children with cystic fibrosis

BACKGROUND: Suboptimal growth and nutritional status are common among children with cystic fibrosis (CF) and pancreatic insufficiency (PI). A better understanding of energy balance is required to improve prevention and treatment of malnutrition. OBJECTIVE: Our objective was to characterize energy balance and the reporting accuracy of dietary intake in children with CF by evaluating the relations between energy intake (EI), energy expenditure (EE), fecal energy loss, nutritional status, and growth. DESIGN: The subjects were participants of a 24-mo prospective study of children 6-10 y of age with CF and PI. EE, EI, fecal energy loss, and anthropometric measures were obtained at baseline and at 24 mo. RESULTS: The children (n = 69) had suboptimal growth at baseline (x +/- SD: weight-for-age z score, -0.53 +/- 1.19; adjusted height-for-age z score, -0.67 +/- 1.06; body mass index z score, -0.29 +/- 1.12), and these variables remained suboptimal at 24 mo. The median ratios of EI to EE at baseline and 24 mo were 1.15 and 1.18, respectively, which decreased to 1.09 and 1.10, respectively, when adjusted for fecal energy loss (EI(-FL):EE). At baseline, 7% of subjects were underreporters, 64% were accurate reporters, and 23% were overreporters of energy intake; the percentages were similar at 24 mo. CONCLUSIONS: Although EI(-FL):EE ratios were higher than expected at both baseline and 24 mo, this cohort showed only age-appropriate weight gain. Self-reported dietary intake data at the individual level should be interpreted with caution, and weight gain velocity may serve as an objective measure of long-term energy balance.     

Nutrition counseling increases weight gain among Brazilian children.

To assess the impact on child growth of the nutrition-counseling component of the Integrated Management of Childhood Illnesses (IMCI) strategy, a randomized trial was implemented. All 28 government health centers in a Southern Brazil city were paired according to baseline nutritional indicators. One center from each pair was randomly selected and its doctors received 20-h training in nutrition counseling. Thirty-three doctors were included and 12-13 patients < 18 mo of age from each doctor were recruited. The study included testing the knowledge of doctors, observing consultations and visiting the children at home 8, 45 and 180 d after the initial consultation. Maternal knowledge, practices and adherence to nutritional recommendations were assessed, and anthropometric measurements were taken. Day-long dietary intake was evaluated on a subsample of children. Doctors in the intervention group had better knowledge of child nutrition and improved assessment and counseling practices. Maternal recall of recommendations was higher in the intervention than in the control group, as was satisfaction with the consultation. Reported use of recommended foods was also increased. Daily fat intake was higher in the intervention than in the control group; mean daily intakes of energy and zinc also tended to improve. Children 12 mo of age or older had improved weight gain and a positive but nonsignificant improvement in length. Nutrition-counseling training improved doctors' performances, maternal practices and the diets and weight gain of children. The randomized design with blind outcome evaluation strongly supports a causal link. These results should be replicated in other settings.     

Influence of dietary fat on the nutrient intake and growth of children from 1 to 5 y of age: the Special Turku Coronary Risk Factor Intervention Project

BACKGROUND: Excessive decreases in fat intake in young children have been linked with low intakes of energy and nutrients and possible growth failure. OBJECTIVE: We evaluated nutrient intakes and growth of healthy children with different fat intakes during the first 5 y of life. DESIGN: In the Special Turku Coronary Risk Factor Intervention Project (STRIP), 7-mo-old children were randomly assigned to an intervention aimed at reduced consumption of saturated fat and cholesterol (n = 540) or to a control group (n = 522). This analysis comprises data for children for whom > or = 6 of 8 possible 3-4-d food records were available (n = 730; 353 females). Children were divided according to fat intake pattern (percentage of energy) between the ages of 13 mo and 5 y into groups with continuously high fat intake (5% of children), increasing fat intake (5%), continuously low fat intake (5%), decreasing fat intake (5%), and average fat intake (80%). Children's energy and nutrient intakes and growth were then compared by analysis of variance. RESULTS: Fat intake at 13 mo of age was particularly low (21% of energy) in the increasing fat intake group and in the continuously low fat intake group (22% of energy at 13 mo; 26% of energy at 5 y). Growth of children in all 5 fat intake groups, however, was not significantly different throughout the study period. Intakes of vitamins and minerals, except of vitamin D, met recommended dietary allowances in all fat intake groups. CONCLUSION: Nutrient intakes and growth were not significantly different in children whose fat intake patterns differed between 13 mo and 5 y of age.     

Energy utilization of breast-fed and formula-fed infants

Breast-fed and formula-fed infants (n = 65) were studied at 1 and 4 mo of age to elucidate differences in energy utilization between feeding groups. Gross energy intake at 1 mo was comparable between groups but was statistically different at 4 mo. Weight, length, and weight gain were not different between groups. Energy expenditure 0-4 h postprandially did not differ between feeding groups. Sleeping metabolic rates (SMRs) were not different but minimal observable energy expenditures standardized by weight were lower among 4-mo-old breast-fed infants (p less than 0.03). No differences were found between feeding groups in thermic effect of feeding (TEF). Activity patterns revealed that breast-fed infants slept less than formula-fed infants (p less than 0.04). Disparities in energy intake observed between breast-fed and formula-fed infants at 4 mo of age did not result in statistically significant differences in growth rate, SMR, or TEF.     

Effects of Early Weight Gain Velocity,Diet Quality,and Snack Food Access on Toddler Weight Status at 1.5 Years: Follow-Up of a Randomized Controlled Infant Formula Trial

This study followed children who participated in a feeding trial in which the type of randomized infant formula fed from 2 weeks significantly affected weight gain velocity during the first 4 months and weight-for-length Z (WLZ) scores up to 11.5 months. We focused on measures of anthropometry, dietary intakes, and parenting related to the provision of snack foods that were collected at the end of the trial (1 year) and the 1.5 years follow-up visit. We not only describe what toddlers are eating, but we also determined the independent and/or interactive effects of randomized formula group, early weight gain velocity, the nutrient content of the post-formula diet, and maternal snack food practices, on toddlers’ weight status. Diet quality underwent drastic changes during this 6-month period. As infant formula disappeared from the diet, fruit and 100% fruit juice intake increased slightly, while intake of “What We Eat in America” food categories sweetened beverages and snacks and sweets more than doubled. Added sugars accounted for 5% of energy needs at 1 year and 9% at 1.5 years. Generalized linear mixed models revealed that, independent of the randomized formula group, greater velocities of weight gain during early infancy and lower access to snacks as toddlers predicted higher WLZ and a greater proportion of toddlers with overweight at 1.5 years. Energy and added sugar intake had no significant effects. These findings add to the growing body of evidence that unhealthy dietary habits are formed even before formula weaning and that, along with improving early diet, transient rapid weight gain and parental feeding practices are modifiable determinants that may reduce risks for obesity.     

A double-blind, randomized, clinical trial of the effect of vitamin A and zinc supplementation on diarrheal disease and respiratory tract infections in children in Mexico City, Mexico

BACKGROUND: The efficacy of micronutrient supplementation in improving childhood health and survival in developing countries may be specific to the micronutrient used and health outcome measured. OBJECTIVE: We evaluated the effect of vitamin A and zinc supplementation on overall rates of childhood diarrheal disease and respiratory tract infections and rates stratified by household and personal characteristics. DESIGN: A double-blind, randomized, placebo-controlled trial was carried out in which 736 children aged 6-15 mo living in a periurban area of Mexico City were assigned to receive vitamin A every 2 mo, zinc daily, vitamin A and zinc together, or placebo. Children were followed for 12 mo to determine overall counts of diarrheal episodes and respiratory tract infections. RESULTS: Vitamin A supplementation was associated with a 27% increase in diarrheal disease [risk ratio (RR): 1.27; 95% CI: 1.10, 1.45; P < 0.001] and a 23% increase in cough with fever (RR: 1.23; 95% CI: 1.02, 1.47; P = 0.02), whereas zinc had no effect on these outcomes. Vitamin A supplementation decreased diarrhea in children from households with dirt floors but increased diarrhea in children from households with nondirt floors, piped water, and indoor bathrooms. Zinc supplementation decreased diarrhea in children from households with dirt floors and whose mothers were more educated. Vitamin A supplementation increased cough with fever in children from less-crowded households that lacked indoor bathrooms and in children of less-educated mothers. CONCLUSIONS: Vitamin A increases diarrheal disease and respiratory tract infections in young children in periurban areas of Mexico City. Vitamin A and zinc have more heterogeneous effects in different subgroups of children.     

Growth and micronutrient status in children receiving a fortified complementary food

Linear growth retardation and anemia are the most prevalent nutritional problems in the world; effective interventions are urgently needed. We evaluated Ecuador's National Food Nutrition Program (PANN 2000) that included a micronutrient-fortified complementary food (FCF), Mi Papilla, in poor periurban and rural communities of Ecuador. The program is preventive and targeted to all infants and young children living in poor communities and receiving government health services. We compared dietary intake, micronutrient status, and growth over 11 mo in a cohort of children from the catchment areas of the PANN 2000 with same-age control children in nearby communities eligible to enter the program 1 y later. PANN 2000 children enrolled in the program when they were age 9-14 mo and were age 20-25 mo at the final survey. They consumed significantly more energy, protein, fat, iron, zinc, vitamin A, and calcium than control children because of their FCF consumption. Anemia, 76% in both groups at baseline, fell to 27% in PANN 2000 children but only to 44% in control children (P < 0.001). The odds of being anemic were 58% lower for PANN 2000 children (P = 0.003). The effects on linear growth and weight were limited to children who were older when the program began (12-14 mo) and were significant for weight (interaction with age, 0.38 kg; P = 0.029) and positive but not significant for length (0.66 cm; P = 0.08). An FCF, including ferrous sulfate, delivered through public health services, is highly effective in improving weight and hemoglobin and reducing anemia.     

Reduction in energy expenditure after liver transplantation.

After successful liver transplantation (LTx), excessive weight gain is common among recipients. This rapid change in body morphology has been attributed to immunosuppressive regimens. The liver's role as a metabolic sensor and its autonomic innervation are pivotal in relaying humoral and neural information to the hypothalamus, where ingestive behavior is determined and has largely been ignored. We examined and assessed the contribution of drugs, energy intake, and energy expenditure on weight gain after LTx. Twenty-three patients were followed up at 3-mo intervals after LTx. Energy expenditure was measured by indirect calorimetry and dietary intake by diet diaries, and body composition was assessed with anthropometry and multifrequency bioelectrical impedance analysis. Cumulative drug doses were calculated, and associations between body composition and immunosuppressive regimens and energy expenditure were examined. Nine months after LTx, 20 of 23 (87%) recipients were overweight or obese, despite three-fourths of this cohort being on weight-reduction regimens. After LTx, a decrease in measured energy expenditure was observed (60.3 +/- 1.6 kJ/kg of body cell mass pre-LTx versus 53.7 +/- 2.2 kJ/kg of body cell mass after 9 mo; P < 0.05). Multiple stepwise regression analysis showed that, when adjusted for body weight, the strongest predictor of fat mass at 9 mo after LTx was resting energy expenditure. Weight gain after LTx is not predicted by immunosuppressive drug dosage. The strong association between weight gain and energy economy might be a consequence of the loss of hepatic metabolic integration and accelerated further by increased energy intake. Effective management of weight gain will not be achieved until the mechanisms involved in altered energy homeostasis are elucidated.     

Determinants of pregnancy outcome and newborn behavior of a semirural Egyptian population

Several potential determinants of birth weight and neonatal behavioral organization, ie, maternal anthropometry, food intake (energy, protein, and plant- and animal-source foods), morbidity, and household socioeconomic status, were followed systematically in a semirural Egyptian population during greater than or equal to 6 mo of pregnancy. In early pregnancy mothers were generally normal weight to moderately overweight. Their mean energy intake, largely from plant sources, was approximately 8.37 MJ/d (2000 kcal/d) during trimesters 2 and 3. Early (3 mo) pregnancy weight and weight gain during trimesters 2 and 3 were significantly positively related to birth weight Z scores. The best predictor model examined for birth weight included early pregnancy weight, weight gain, and length of gestation (R2 = 0.45). Early pregnancy weight and maternal intake of animal-source foods were significant positive predictors of the newborn's orientation and habituation behavior, respectively. Habituation and orientation measures assess the infant's early ability to process information.     

The diets of preschool children in Newcastle upon Tyne, 1968-71.

1. Ninety-one families containing 140 children under 4 years of age at enrolment were studied. At 1-monthly intervals, the children were weighed and measured and qualitative information about feeding habits was obtained. Weighed dietary surveys for periods of 5 d were made at approximately 8 months, 3 years, and 5 years of age; there were forty-six failures in 260 surveys attempted. 2. At the four specified ages, mean energy intakes were 3-75, 5-03, 5-82 and 6-75 MJ (896, 1203, 1392 and 1613 kcal)/d respectively. At 8 months, milk products provided on average, 43% of the total energy intake, and commerical baby foods provided 17%. These values decreased to 21 and 2% respectively at 20 months and there was little further change therafter. 3. Average intake of energy and of most nutrients met recommended intakes (Department of Health and Social Security, 1969). Iron intakes were marginal, and vitamin D intakes were low. 4. The energy intake of boys was significantly higher than that of the girls at 3 years of age, but the boys were not significantly heavier. The energy intake of children from "manual-worker" families was higher than that from "non-manual" families. Similarly, the energy intake of children from larger families was higher than that of children from smaller families. 5. Energy intakes were correlated with body-weights and with rates of gain in weight. Irrespective of body-weight, "big eaters" at 20 months tended to be "big eaters" at 3 years also.     

Zinc during and in convalescence from diarrhea has no demonstrable effect on subsequent morbidity and anthropometric status among infants <6 mo of age

BACKGROUND: Preventing illness and improving growth in the first 6 mo of life is critical to reducing infant mortality. Zinc given for 14 d at the start of diarrhea has been shown to decrease the incidence and prevalence of diarrhea and pneumonia and improve growth in the 2-3 mo after, but no trial has been done in infants <6 mo of age. OBJECTIVE: This study sought to assess the effect of 14 d of zinc supplementation on subsequent morbidity and growth among infants 1-5 mo of age living in Pakistan, India, and Ethiopia. DESIGN: Infants with acute diarrhea were randomly assigned to receive zinc (10 mg/d; n = 538) or placebo (n = 536) for 2 wk. Weekly follow-up visits were conducted for 8 wk after the diarrhea episode. Incidence and prevalence of diarrhea and prevalence of respiratory infections including pneumonia were compared between the groups. Changes in weight, length, and corresponding z scores during the 8 wk of follow-up were also compared. RESULTS: One thousand seventy-four infants were enrolled at the start of follow-up. The groups did not differ significantly in the proportion of infants with at least one episode of diarrhea or respiratory infections. Infants who received zinc had more days of diarrhea (rate ratio = 1.20) than did the infants who received placebo. The groups had similar prevalences of pneumonia and overall respiratory infections. No significant differences in the mean changes in weight-for-age, length-for-age, and weight-for-length z scores were observed between the groups overall or in stratified analyses. CONCLUSION: Young infants do not appear to benefit from 2 wk of zinc, unlike what has been observed among older children.     

Thyroid function and energy intake during weight gain following treatment of hyperthyroidism

OBJECTIVE: Individuals with hyperthyroidism lose weight despite increased appetite and food intake, and weight is regained after treatment of hyperthyroidism. We asked whether this weight regain is purely a function of lowered metabolic rate coincident with lowered thyroid hormone concentrations or if the weight gain is related to food-energy overconsumption. METHODS: Ten unselected patients with hyperthyroidism treated with 131I were studied. The following measurements were made at 0, 1, 2, 3, 6, and 12 months: total food energy, carbohydrate, fat and protein consumption; serum thyroxine (T4); serum triiodothyronine (T3); T3 resin uptake; serum thyroid stimulating hormone (TSH); weight; height; and 24-hour urinary urea excretion. RESULTS: Inverse changes in body weight and food energy consumption/kg throughout the period of observation was a striking finding (mean initial weight 67.1+/-5 kg, final weight 76.4 kg+/-3 kg, premorbid weight 77.1+/-5 kg). The initial and final food energy intake was 3005+/-199 and 2597+/-137 Kcal/24 hrs, respectively. The thyroid hormone concentrations declined inversely relative to weight gain during the first months of the study, but later the thyroid hormones increased while weight gain continued. Initial serum T4 15.0+/-1 value at three months was 4.0+/-1.0 mg/dl, final T4 11.0+/-1. CONCLUSION: We conclude that weight gain following treatment of hyperthyroidism is due to 1) reduction in metabolic rate consequent upon the decreased thyroid hormone concentrations and 2) food energy intake which was initially greater than required to maintain individuals' premorbid weight. As body weight increased, food intake declined and both reached an asymptotic limit.     

L-carnitine supplementation does not promote weight loss in ovariectomized rats despite endurance exercise

In this five-week study, we tested the hypotheses that free access to a maintenance diet supplemented with L-carnitine (L-C) would reduce body fat in adult, sedentary, ovariectomized (OVX) rats, and that there would be an additive effect of L-C on weight reduction in swim-trained animals. As expected, serum carnitine was higher in rats fed the L-C diet, and the OVX-induced weight gain and abdominal fat were counteracted by swimming. L-C supplementation did not reduce the weight gain or abdominal fat in these adult female rats, Moreover, though not reaching statistical significance, rats that were fed L-C demonstrated a tendency for greater weight gain than their basal-fed counterparts despite no difference in energy intake. If the results of this study on ovariectomized rats can be translated to postmenopausal women, moderate intensity exercise may be recommended, but L-C supplementation, with no energy restriction, may be contraindicated as a weight loss method in this cohort.     

Randomized controlled trial of the effect of daily supplementation with zinc or multiple micronutrients on the morbidity, growth, and micronutrient status of young Peruvian children

BACKGROUND: Zinc supplements reduce childhood morbidity in populations in whom zinc deficiency is common. In such populations, deficiencies in other micronutrients may also occur. OBJECTIVE: The objective was to determine whether the administration of other micronutrients with zinc modifies the effect of zinc supplementation on children's morbidity and physical growth. DESIGN: Two hundred forty-six children aged 6-35 mo with persistent diarrhea were randomly assigned to 1 of 3 groups to receive a daily supplement of 10 mg Zn alone (Zn; n = 81), zinc plus vitamins and other minerals at 1-2 times recommended daily intakes (Zn+VM; n = 82), or placebo (n = 83) for approximately 6 mo after the diarrhea episode ended. Morbidity information was collected on weekdays. Weight, length, and other anthropometric indicators were measured monthly, and plasma zinc and other indicators of micronutrient status were measured at baseline and 6 mo. RESULTS: Supplement consumption was high ( approximately 90%) in all groups, although slightly more vomiting was reported in the Zn+VM group (P < 0.0001, analysis of variance). The change in plasma zinc from baseline to 6 mo was greater in the 2 zinc groups (6.1, 27.3, and 16.2 micro g/dL in the placebo, Zn, and Zn+VM groups, respectively; P < 0.0001, analysis of variance). The Zn group had fewer episodes of diarrhea, dysentery, and respiratory illness and a lower prevalence of fever and cough than did the Zn+VM group and a lower prevalence of cough than did the placebo group (P = 0.05). No significant effects of supplementation on growth were observed. CONCLUSION: Morbidity was greater after supplementation with zinc plus multivitamins and minerals than it was after supplementation with zinc alone.
