The role of child care settings in obesity prevention.

Mary Story, Karen Kaphingst, and Simone French argue that researchers and policymakers focused on childhood obesity have paid insufficient attention to child care. Although child care settings can be a major force in shaping children's dietary intake, physical activity, and energy balance-and thus in combating the childhood obesity epidemic-researchers know relatively little about either the nutrition or the physical activity environment in the nation's child care facilities. What research exists suggests that the nutritional quality of meals and snacks may be poor and activity levels may be inadequate. Few uniform standards apply to nutrition or physical activity offerings in the nation's child care centers. With the exception of the federal Head Start program, child care facilities are regulated by states, and state rules vary widely. The authors argue that weak state standards governing physical activity and nutrition represent a missed opportunity to combat obesity. A relatively simple measure, such as specifying how much time children in day care should spend being physically active, could help promote healthful habits among young children. The authors note that several federal programs provide for the needs of low-income children in child care. The Child and Adult Care Food Program, administered by the Department of Agriculture, provides funds for meals and snacks for almost 3 million children in child care each day. Providers who receive funds must serve meals and snacks that meet certain minimal standards, but the authors argue for toughening those regulations so that meals and snacks meet specific nutrient-based standards. The authors cite Head Start, a federal preschool program serving some 900,000 low-income infants and children up to age five, as a model for other child care programs as it has federal performance standards for nutrition. Although many child care settings fall short in their nutritional and physical activity offerings, they offer untapped opportunities for developing and evaluating effective obesity-prevention strategies to reach both children and their parents.

Calorie intake and meal patterns up to 4 years after Roux-en-Y gastric bypass surgery.

BACKGROUND: Roux-en-Y gastric bypass (RYGBP) is the most popular surgical treatment for morbid obesity in the U.S.A., producing significant and durable weight loss with improvement in co-morbidities. Although a greater number of patients are undergoing surgical treatment for obesity, little data are available regarding their food intake after surgery. This study was undertaken to evaluate the caloric amount, nutrient composition and meal patterns of patients 18 months to 4 years after RYGBP. Ethnic differences in food intake were also investigated. METHODS: Questionnaires were mailed to 360 patients who had undergone RYGBP at least 18 months prior to the onset of the study. RESULTS: Data were available from 69 patients, 52% Caucasian, 25% African-American, 23% Hispanic. 30 months after surgery, the average daily calorie intake was 1733 +/- 630 kcal (n=68, range 624-3486 kcal), with 44% of calories from carbohydrates, 22% from protein and 33% from fat. Sugar-sweetened beverages represented 7% of total caloric intake. Patients consumed 3 meals and 3 snacks per day on average. Food intake from dinner and an evening snack represented 40% of the daily caloric intake. Snacks accounted for 37% of the daily intake. Percent excess weight loss (%EWL) was 58 +/- 17% and was not different among ethnic groups. However, Hispanics reported consuming fewer snacks and fewer calories. %EWL correlated with the total daily caloric intake (r= .446, P <0.001). Follow-up attendance was 54% at 1 year after surgery but fell to 10% at 3 years. Only 77% of patients were taking vitamin supplements. CONCLUSION: RYGBP resulted in significant weight loss. Caloric intake was quite variable. Long-term follow-up remained low, putting patients at risk for metabolic and vitamin deficiencies. The relationship between caloric intake and long-term weight changes remains to be studied.

Lispro or regular insulin for multiple injection therapy in adolescence. Differences in free insulin and glucose levels overnight.

OBJECTIVE: Regular insulin given with the evening meal could contribute to the risk of nocturnal hypoglycemia in adolescents with type 1 diabetes using a multiple injection regimen. To test this hypothesis, we compared glucodynamics and free insulin levels on two separate study nights. RESEARCH DESIGN AND METHODS: A total of 14 adolescents were recruited. On both nights, identical doses of regular insulin or insulin lispro were administered 30 min or 10 min, respectively, before the evening meal, using a double-blind randomized crossover study design. Doses of NPH insulin and carbohydrate content of the evening meal and snack were kept identical. Blood samples were taken every 15 min for blood glucose and every 60 min for free insulin and ketones. RESULTS: After insulin lispro administration, glucose levels were significantly lower between the evening meal and the bedtime snack (analysis of variance [ANOVA] P = 0.02), and four hypoglycemic episodes were recorded. This corresponded to a higher (458 +/- 48 vs. 305 +/- 33 pmol/l, P = 0.02), earlier (64 +/- 4.6 vs. 103 +/- 12 min, P = 0.01), and shorter-lasting (245 +/- 21 vs. 365 +/- 39 min, P = 0.01) insulin peak in contrast to regular insulin. After the bedtime snack, glucose levels increased dramatically during the lispro night and stayed higher, up to 0300 in the morning (ANOVA P = 0.01), corresponding to lower mean insulin levels (146 +/- 20 vs. 184 +/- 27 pmol/l, P = 0.04). No differences were seen in glucose and insulin levels between 0300 and 0800. Four episodes of nocturnal hypoglycemia were documented after the bedtime snack during the regular insulin night, in contrast to one episode after insulin lispro. No differences in ketone levels were observed. CONCLUSIONS: The replacement of regular insulin with insulin lispro may reduce the risk of late hypoglycemia, but redistribution of the evening carbohydrate may be needed to ensure good metabolic control and prevent early postprandial hypoglycemia.

[Breakfast among students of compulsory secondary education].

GOAL: To study the breakfast model of a rural population of obligatory secondary education (ESO) and to analyze the energy and nutrients provided, in connection with established nutritional requirements. MATERIAL AND METHODS: Randomized year-stratified distribution of a semi-quantitative questionnaire on the frequency of food intake for breakfast (on rising and mid-morning snack) to 400 ESO students: 188 males (47%) and 212 females (53%), aged between 13 and 16 years. The densities of nutrients have been calculated in proportion to established dietary recommendations (%RDA). RESULTS: 93.2% had breakfast on rising and 83.8% took a mid-morning snack on a daily basis. The most common foods were milk (89.3%) and sweet food (45.7%) for the first breakfast and a sandwich with cold meats an/or cured ham (74.6%) at mid-morning. The mean %RDA of the calorie intake was 30.6% in males and 36.1% in females (n.s.). The mean %RDA of the cholesterol intake was 54.3% in males and 48.6% in females (n.s.). The %RDA for calcium, vitamin A, vitamin C and vitamin B12 were greater (p < 0.05) in early breakfasts, whereas the %RDA of iron intake, vitamin B1 and niacin were greater (p < 0.05) in the snack. CONCLUSIONS: This breakfast model, while providing an appropriate provision of energy, differs from the prototype of a healthy diet through an excessive consumption of refined sugars (early breakfast) and meat and derivatives (snack) with a deficit in cereals and fruit. It would be necessary to encourage dietary advice in Primary Health Care programmes, as well as to develop food and nutrition programmes within compulsory education.

[Relationships between infant lifestyle and adolescent obesity. The Enzan maternal-and-child health longitudinal study].

OBJECTIVE: A longitudinal study was analyzed to clarify relationships between infant lifestyle, obesity, features of family life and adolescent obesity. SUBJECTS AND METHODS: Subjects in the present study were born between April 1987 and March 1991, in Enzan City, Yamanashi prefecture. Infant height and weight were measured and questionnaires were collected at medical check-ups at 1.5- and 3-year-of age. Adolescent height and weight were measured in April 2000. Obese adolescents were defined as those with on obesity index > or = 20%. RESULTS: At 1.5-years-of age, 883 responses to the questionnaire were obtained, and 737 subjects were followed to adolescence (83.5%). Mean follow-up period was 10 years 11 months. A high Kaup index at 1.5-years-of age (odds ratio (OR) 2.61; 95% confidence interval (CI) 1.11-6.12) and when 3-years-of age (OR 5.34; CI 2.54-11.23), as well as maternal obesity (OR 5.32; CI 2.67-10.60) represented risk factors for adolescent obesity. Of the lifestyle items, "playing alone inside" at 1.5-years-of age (adjusted OR 3.01; CI 1.01-8.99) and "taking snacks without time constraints" at 3-years-of age (adjusted OR 2.12; CI 1.25-3.61) were additional risk factors. In food items, only low intake of cow's milk displayed a significant relationship with adolescent obesity, the link being negative with an adjusted OR of 0.63 (CI 0.41-0.95). Covariance structural analysis was performed and a causal model was constructed. Maternal obesity, obesity at 3-years-of age, playing alone inside, taking snacks without time constraints, and low intake of cow's milk were all associated with obesity in infancy. Maternal obesity affected methods of answering child demands, in turn affecting snacking habits. CONCLUSIONS: Adolescent obesity displays relationships with maternal obesity, a high Kaup index in infancy, play activity, snacking habits, and intake of cow's milk. Although genetic factors exert a strong influence, these components of infant lifestyle all play a role in the development of adolescent obesity.

[The relationship between dental caries of deciduous teeth and anxiety of mothers associated with child-care].

AIM: The incidence of caries in children is closely related to daily habits and may also be influenced markedly by a mother's attitude to child-care. For example, if a mother has a mental health problem such as child-care anxiety, this may prevent her obtaining advice on the daily health requirements of her children including the need to brush the teeth regularly. It is therefore important that mothers receive guidance in order to minimize the incidence of caries. This study examined the effect of child-care anxiety in mothers on the prevalence of caries in 3-year-old children. METHODS: The subjects were 503 pairs of mothers and their children who attended a check-up at a community health center in Gifu City when the children were aged 3-years. The mothers answered a questionnaire about child-care, while the children had a dental examination and caries activity test (Cariostat). The prevalence of caries and the Cariostat score were examined by binomial logistic regression analysis. The relationship between child-care anxiety of the mothers and children's caries or Cariostat score were analyzed using Covariance Analysis, that incorporated additional multiple indicator models including snack behavior, social-support and food faddism of the children. RESULTS: 1. The rate of caries disease increased with high Cariostat scores and was statistically significant at scores greater than 2.0. 2. Covariance analysis demonstrated both the models of children's caries and Cariostat score provided a good fit to the actual data, the former model having a GFI = 0.951 and RMSEA = 0.046, and the latter a GFI = 0.952 and RMSEA = 0.046. 3. It was found that anxiety over child-care directly affected snack behavior, while itself being influenced directly by both social-support and food fads of the children. 4. Snack behavior influenced Cariostat score, but not the prevalence of child caries. CONCLUSIONS: We suggest it is necessary to provide guidance to mothers with a background of child-care anxiety in order to prevent a high rate of caries in their children. It may be possible to detect mothers with child-care anxiety that leads to bad snack behavior by obtaining information on the child's social-support and food fads. Our study showed that offering social support was an effective means of preventing habits that may predispose to the development of dental caries. Furthermore, we found the Cariostat score was an effective test for assessing the influence of child-care on caries incidence.

Competitive foods and beverages available for purchase in secondary schools--selected sites, United States, 2004.

The percentage of overweight youths aged 12-19 years in the United States more than tripled from 5% during 1976-1980 to 16% during 1999-2002. Overweight youths are at increased risk for cardiovascular consequences and other serious physical and psychosocial health problems. Because most youths are enrolled in school, the school nutrition environment is integral to any strategy to improve dietary behavior and reduce overweight among youths. In most schools, the nutrition environment has two components: the U.S. Department of Agriculture (USDA) school meals program and the sale of competitive foods. USDA defines competitive foods as those foods and beverages, regardless of nutritional value, sold at a school separate from the USDA school meals program. To identify the types of competitive foods and beverages available for purchase from school vending machines or at school stores, canteens, or snack bars, CDC analyzed data from the 2004 School Health Profiles for public secondary schools in 27 states and 11 large urban school districts. This report summarizes the results of that analysis, which indicated that, in 2004, the majority of secondary schools (median across states: 89.5%; median across large urban school districts: 81.5%) allowed students to purchase snack foods or beverages from vending machines or at the school store, canteen, or snack bar. In addition, the percentage of schools offering certain types of snack foods and beverages varied across states and large urban school districts. Although the majority of schools offered some nutritious foods and beverages in these settings, the majority of schools also offered less nutritious choices. Educators, families, and school and public health officials should work together to provide school nutrition environments that will help improve dietary behavior and reduce overweight among youths.

[Atherogenic trans isomers of fatty acids in some food products].

OBJECTIVE: Trans isomers of fatty acids (TFA) contain double bonds in their molecular structure with the trans configuration. Food products prominent for their TFA content include plant oils (margarine), mayonnaise, products baked with plant oils, and ready-made glazes and icings. The so-called fast foods and snacks (bars, chips) represent a significant source of TFA, particularly for children and youth. Considering the potentially atherogenic properties of TFA, this work was undertaken to determine the content of the principal monounsaturated TFA in some food products ubiquitous on the market, i.e. margarines and snacks. MATERIAL AND METHODS: We studied bars (Snickers, Mars, Twix), chips (Lay's, Snack, Cheetos), and margarines (Rama Classic, Rama Olivio, Vita, Flora, Finea, Delma, Masmix, Krówka, Smakowita with butter, Extra Pomorskie). The content of TFA was determined with gas chromatography. RESULTS: The highest content ofmonounsatured TFA among sweets was disclosed for the Twix bar (2.94 microg/g), while the lowest for Snickers (0.3 microg/g). Among margarines, the highest content of TFA was found for Smakowita with butter (87.6 microg/g), Krówka (46 microg/g), and Vita (38.7 microg/g), whereas the content was lowest in Finea (0.12 microg/g) and Delma (0.14 microg/g). In the case of chips, the content was highest for Cheetos (3.5 microg/g) and lowest for Snack (0.09 microg/g). CONCLUSIONS: The content of atherogenic TFA in common food products varies widely. In some cases, the content of TFA is considerable and unjustly undisclosed by manufacturers. Promotion of these products should include information in respect of TFA. This conclusion is of particular importance considering the significance of these products in the diet of children and youth.

Children's frequency of consumption of foods high in fat and sodium.

We administered a food frequency instrument to third-fifth grade students (n = 943) in four Texas schools. Comparison of foods reported on the food frequency questionnaire and on 24-hour dietary recalls (n = 7) produced a percent agreement of 83.3. The most frequent 25 foods accounted for 64.0% of food choices across all meals, 93.5% of breakfast choices, 76.4% of lunch choices, 70.5% of supper choices, and 76.0% of snack choices. Breads, milk, hamburger or steak, soda pop, tomato sauce or tomatoes, and cheese were the most frequently consumed foods. Fruits and juices accounted for 6.1% of total selections for boys and 6.6% for girls, while vegetables accounted for 15.7% of total selections for boys and 16.2% for girls. Fruit was more likely to be consumed for snacks than for meals, and vegetables were consumed in about the same frequency at lunch and supper and for snacks. We analyzed the total fat, saturated fat, and sodium content of the most frequently consumed foods. Seventeen of the top 25 foods for the total day and 13-16 for each meal or snack exceeded by at least 50% the recommended levels for fat, saturated fat, or sodium. The pattern of consumption was one of frequent consumption of a relatively small number of foods, many of which are high in fat or sodium.

Effect of fat- and sucrose-containing foods on the size of eating episodes and energy intake in lean males: potential for causing overconsumption.

OBJECTIVE: This study compared the action of sucrose- and fat-containing foods on the size of eating episodes (satiation) and postingestive energy intake (satiety). DESIGN: The study was a 2 x 2 within-subjects design, each subject received each of four conditions in a counterbalanced order. SETTING: The study was carried out in the Human Appetite and Nutrition Research Unit. SUBJECTS: Eighteen normal-weight young male University students. INTERVENTIONS: Subjects consumed a low (2238 kJ) or high (3962 kJ) energy lunch followed 2 h later by the opportunity to eat freely from an ad libitum selection of high fat, low sucrose or high sucrose, low fat snacks. Visual analogue rating scales to record subjective feelings of hunger, fullness and related sensations were completed periodically through the test day. RESULTS: When offered a high sucrose, low fat selection of snacks subjects consumed less energy than when offered a high fat, low sucrose selection (P < 0.0001). However postingestive satiety was similar. The energy intake of snacks consumed was also determined by hunger; the low energy lunch gave rise to a higher level of hunger and greater intake (P < 0.01). Energy intake for the total day was significantly more when high fat, low sucrose snacks were consumed (P < 0.001). CONCLUSIONS: These results have indicated that the size of an eating episode is influenced by the level of hunger and the nutrient composition of the foods consumed. High fat foods (probably due to higher energy density) lead to a passive overconsumption which generates a relatively weak satiety.

Contribution of foodservice programs in preschool centers to children's nutritional needs.

Seven-day nutrient intakes of 517 Head Start and day care children participating in USDA's Special Food Service Programs for Children in Nebraska, Kansas, and Texas were assessed. Protein, vitamin A, and ascorbic acid levels from diets served at the centers were judged to be adequate, while calories and B vitamins were below recommendations but proportional to each other. Calcium intake from center diets did not increase proportionately as the number of meals and snacks increased. Nutrient contributions were only slightly greater from center diets when two meals and two snacks were provided than when one meal and one snack were served. Home diets made substantial contributions to the diets of all children, resulting in little difference in total nutrient intakes between children receiving fewer or more meals and snacks at the centers. Iron was the nutrient supplied in least amount in relation to recommendations, when intakes from home and center were combined.

Food intake in the daily environment after energy-reduced lunch, related to habitual meal frequency.

Twenty women were offered two energy-reduced lunches in 48 h and five similar normal-energy lunches within a week, with snacks and evening meals provided and their own standard breakfasts. The subjects were categorized as "nibblers" or "gorgers" (10 per group), by the criterion of habitual eating of "snacks" between mealtimes. Compensatory energy intake occurred in the nibblers within 5 h of the "light" lunch. In the gorgers compensation of energy intake was not reached within 48 h. We conclude that differences in short-term compensation of intake can arise from habitual snacking or its absence.

Meal pattern and nutrient intake among adult Finns.

The purpose of this study was to investigate the relationship between meal pattern and diet. Nutrient contents of meals, snacks and other eating occasions were compared and differences in dietary intake analysed between respondents following a conventional meal pattern and others. A random sample of 1861 adults aged 25-64 from four regions of Finland completed a mailed questionnaire and 3-day food record in the spring of 1992. A conventional meal pattern was defined on the basis of national dietary guidelines as including breakfast, warm lunch and warm dinner, and subjects were identified with the help of the questionnaire. Meals and snacks were defined according to the respondents subjective criteria. Forty-four percent of all respondents followed the conventional meal pattern. Meal pattern has no effect on nutrient intake in men and small effects in women. Women following the conventional meal pattern had higher energy and cholesterol intake and lower alcohol and vitamin C intake than other women. Meals contributed to energy, protein and fat intake, and snacks to sugar and alcohol. Meal pattern had only a small effect on diet and conventional meal pattern cannot be considered healthier than other meal patterns.

Predicting Hunger: The Effects of Appetite and Delay on Choice.

Preferences often fluctuate as a result of transient changes in hunger and other visceral states. When current decisions have delayed consequences, the preferences that should be relevant are those that will prevail when the consequences occur. However, consistent with the notion of an intrapersonal empathy gap (Loewenstein, 1996) we find that an individual's current state of appetite has a significant effect on choices that apply to the future. Participants in our study made advance choices between healthy and unhealthy snacks (i.e., fruit and junk food) that they would receive in 1 week when they were either hungry (late in the afternoon) or satisfied (immediately after lunch). In 1 week, at the appointed time, they made an immediate choice, an opportunity to change their advance choice. Our main predictions were strongly confirmed. First, advance choices were influenced by current hunger as well as future hunger: hungry participants chose more unhealthy snacks than did satisfied ones. Second, participants were dynamically inconsistent: they chose far more unhealthy snacks for immediate choice than for advance choice. An additional hypothesis related to gender differences was also confirmed. Copyright 1998 Academic Press.

Influence factors on the development of obesity in 3-year-old children based on the Toyama study.

BACKGROUND: Obesity in childhood increases the risk of obesity in adulthood. Obesity in adulthood is a risk factor for chronic diseases such as hypertension and atherosclerosis. Therefore, it is important to eliminate factors influencing the development of obesity in children from the viewpoint of preventive medicine. The purpose of this study is to elucidate the relationship between obesity and lifestyle in 3-year-old children in a case-control study. METHODS: Subjects were selected from the Toyama study at health checkups for 3-year-old children which are done routinely by local governments in Japan on all children of that age. A special questionnaire consisting of items on lifestyle and environmental factors of the children and past histories of parents was distributed to the Toyama study participants beforehand and was collected at the checkup. Matched-pair comparisons were performed between obese children whose body mass index was 18 or more (N = 427) and control children (N = 854) matched by sex and birth month. Multivariate stepwise conditional logistic regression analysis was also applied to assess the influence of confounding factors. RESULTS: The following six factors significantly influenced the development of obese 3-year-old children using the Mantel-Haenszel method: the mother's job, limited playtime outdoors (1 hour or less), snacking irregularity, an overweight father (body mass index >/= 24), an overweight mother (body mass index >/= 24), and overweight at birth (birth weight >/= 3,500 g). An overweight mother or father, limited playtime outdoors, overweight at birth, and snacking irregularity were significantly related to obesity in 3-year-old children after adjusting for confounding factors by multivariate stepwise conditional logistic regression analysis. CONCLUSIONS: We have suggested several factors influencing the development of obesity in 3-year-old Japanese children: parental overweight and overweight at birth as host factors, physical inactivity and snacking irregularity as behavioral factors, the mother's job as an environmental factor.

Emotional reactivity, emotional eating, and obesity: a naturalistic study.

Laboratory studies indicate that obese individuals are more emotionally reactive and more likely to overeat when distressed than are those of normal weight. These studies were conducted under highly artificial conditions, however, and their generality outside of the laboratory remains largely untested. The present study compared the emotional reactivity and emotional eating of normal and overweight female college students in the natural environment. Subjects self-monitored their food intake and mood just prior to each instance of eating for 12 consecutive days. The results indicated that obese subjects were more emotionally reactive and more likely to engage in emotional eating than normals, but these findings applied only to snacks, not to meals. Correlational analyses indicated that emotional distress associated with snacks and emotional eating associated with both snacks and meals were related to subjects' percentage overweight. The two groups did not differ on any measure of positive emotions of consumption following positive emotions, nor were these two variables related to percentage overweight. The theoretical and clinical implications of these findings are briefly discussed.

Gastric emptying of indigestible tablets in relation to composition and time of ingestion of meals studied by metal detector.

Enteric-coated tablets leave the stomach mainly during the interdigestive phase. Composition as well as time of ingestion of meals may influence their gastric emptying considerably. In 12 normal volunteers gastric emptying of a plastic tablet with a metal core was followed by a metal detector in relation to different compositions and various times of ingestion of meals. With an empty stomach and after ingestion of 250 ml water, the mean time for gastric emptying of the tablet was 38 +/- 11 min (mean +/- SEM) and 38 +/- 8 min. Two hundred fifty milliliters of milk (652 kJ) and a formula diet (1000 kJ) delayed gastric emptying time to 128 +/- 14 and 152 +/- 6 min, respectively (P less than 0.05). Breakfast (2200 kJ) further retarded gastric emptying compared with both liquids to 249 +/- 24 min (P less than 0.05). There was a close correlation between nutritive density and gastric emptying of the tablet (r = 0.92; P less than 0.001). Main meals also delayed gastric emptying of tablets when compared to empty stomach (P less than 0.05). A snack after breakfast further delayed gastric emptying from 201 +/- 10 to 278 +/- 19 min (P less than 0.05). The largest delay was observed following ingestion of breakfast, lunch, dinner, and additional snacks (509 +/- 220 min). We conclude that the delay of gastric emptying of enteric-coated tablets by food is related to its nutritive density and eating habits. The gastric emptying of an enteric coated tablet that is ingested early in the morning may be delayed until late at night when several meals and snacks are ingested during the day, leading to unwanted alterations in bioavailability and to possible adverse effects.

Mycoflora and aflatoxins in a west African corn-groundnut based convenience food.

A total of 14 fungal species, mostly toxigenic, were isolated from 50 samples of 'donkwa' snack obtained from 16 producers. All of the isolates recorded substantial growth, though at varying rates, on the 2% snack agar provided. They also induced a reduction in the oil and an increase in free fatty acids of the substrate suggesting their participatory roles in deterioration. Most of the snack samples analysed contained initial amounts of aflatoxins above the 'safe' permissible level (30 ppb). The initial toxin levels increased substantially with storage time under 79.5, 89.5 and 100% ambient relative humidities but increased only slightly when samples were kept at 71% relative humidity. Almost constant toxin levels were recorded throughout the study period under 51% relative humidity. Accumulation of aflatoxin B1 in samples was most enhanced at 89.5% relative humidity. Comparatively, greater amounts of aflatoxin B1 accumulated under all conditions than the amounts recorded for aflatoxin G1.
