The Association between Food Insecurity and Diet Quality Varies by Race/Ethnicity: An Analysis of National Health and Nutrition Examination Survey 2011-2014 Results

BackgroundFood insecurity is believed to influence the quality and quantity of foods consumed; however, studies examining food insecurity and diet quality have been inconclusive and few studies have explored variability in these associations by sex and race/ethnicity.ObjectiveThis study examined associations between food insecurity and diet quality, and variations by sex and race/ethnicity.DesignCross-sectional analysis of data from the 2011-2014 National Health and Nutrition Examination Surveys.ParticipantsThe study population was composed of 4,393 adults (aged 20 to 65 years) with family incomes ≤300% of the federal poverty level with complete data on household food security and dietary intake via two 24-hour dietary recalls.Main outcome measuresDiet quality was assessed using the Healthy Eating Index-2015.Statistical analyses performedAssociations between food insecurity and Healthy Eating Index-2015 total and component scores were examined using linear regression models and generalized linear models. Models adjusted for sociodemographic and health covariates.ResultsCompared with food-secure adults, food-insecure adults reported a 2.22-unit lower Healthy Eating Index-2015 score (95% CI –3.35 to –1.08). This association was most pronounced among non-Hispanic whites and adults of Asian or other races/ethnicities. There were no associations among non-Hispanic black or Hispanic adults, and no differences by sex. Among non-Hispanic whites, food insecurity was associated with lower scores for total protein foods, seafood and plant proteins, and added sugar. Among Asians, food insecurity was associated with lower scores for whole fruit.ConclusionsFood insecurity was associated with lower diet quality primarily among non-Hispanic whites; Asians; and other adults, a group composed of American Indian or Alaska Natives, Native Hawaiian or Other Pacific Islanders, and multiracial adults. Further research is needed to better understand the nature of this association among understudied racial/ethnic groups.     

Diet Quality and Fruit,Vegetable, and Sugar-Sweetened Beverage Consumption by Household Food Insecurity among 8- to 12-Year-Old Children during Summer Months

BackgroundSchool-delivered nutrition assistance programs have improved dietary intake for children from food-insecure households during the school year. However, little is known about their diet quality and eating patterns during summer months.ObjectiveSchool-aged children’s summer month weekday and weekend day diet quality and eating patterns were assessed by household food insecurity.DesignSecondary analysis of cross-sectional data was employed.Participants/settingDuring the summers of 2011 through 2017, baseline data were collected from parent–child dyads participating in one of two community-based obesity prevention trials in metropolitan Minnesota (N=218). The mean age of children was 10 years; 50% were girls, 49% were nonwhite, and 25% were from food-insecure households.Main outcome measuresChildren from food-secure and food-insecure households were identified by using the short form of the US Household Food Security Survey. Healthy Eating Index 2015 and eating patterns—including energy intake and consumption of whole fruits, vegetables, 100% fruit/vegetable juice, and sugar-sweetened beverages—were estimated by means of 24-hour dietary recall interviews conducted on weekdays and weekend days.Statistical analysis performedGeneral linear modeling was used to examine diet quality and eating patterns by food insecurity, controlling for child age, child body mass index z score, and parent education.ResultsChildren from food-insecure and food-secure households had Healthy Eating Index 2015 scores less than 50. Children from food-insecure households reported less energy intake, fewer cups of whole fruit, and more sugar-sweetened beverage consumption for every 1,000 kcal consumed on a weekend day when compared with their counterparts from food-secure households (P<0.05). Similar results were not seen for weekday eating patterns.ConclusionsWhole fruit and sugar-sweetened beverage consumption varied by food insecurity on weekend days during summer months. Because children tend to gain weight during summer months, efforts to increase weekend access to whole fruits and promote water consumption may contribute to weight gain prevention and healthy development, especially for children from food-insecure households.     

Food Insecurity Is Inversely Associated with Diet Quality of Lower-Income Adults

Food insecurity acts as a chronic stressor independent of poverty. Food-insecure adults may consume more highly palatable foods as a coping mechanism, leading to poorer diet quality and increased risks of chronic disease over time. Using data from the 1999-2008 National Health and Nutrition Examination Surveys, this study aimed to examine the cross-sectional differences in dietary intake and diet quality by household food security among 8,129 lower-income adults (≤300% of the federal poverty level). Food insecurity was assessed using the 18-item US Household Food Security Survey Module. Dietary intake was assessed from 24-hour recalls and diet quality was measured using the Healthy Eating Index-2005 and the Alternate Healthy Eating Index-2010. Relative mean differences in dietary outcomes by household food security were estimated using linear regression models, adjusting for sociodemographic characteristics. Lower-income food-insecure adults reported higher consumption of some highly palatable foods, including high-fat dairy products (P trend<0.0001) and salty snacks (P trend=0.01) compared with lower-income food-secure adults. Food insecurity was also associated with more sugar-sweetened beverages (P trend=0.003); more red/processed meat (P trend=0.005); more nuts, seeds, and legumes (P trend=0.0006); fewer vegetables (P trend<0.0001); and fewer sweets and bakery desserts (P trend=0.0002). No differences were observed for intakes of total energy and macronutrients. Food insecurity was significantly associated with lower Healthy Eating Index-2005 (P trend<0.0001) and Alternate Healthy Eating Index-2010 scores (P trend<0.0001). Despite no macronutrient differences, food insecurity was associated with characteristics of poor diet quality known to increase chronic disease risk.     

Food Insecurity: Its Relationship to Dietary Intake and Body Weight among Somali Refugee Women in the United States

ObjectiveTo examine the association between food insecurity, dietary intake, and body mass index among Somali refugee women living in the United States.MethodsCross-sectional study utilizing the snowball sampling method.ResultsMost (67%) participants experienced some level of food insecurity, which was common among recent arrivals and those who spoke only Somali at home (P < .05). Intake of meat and eggs was higher, whereas intake of fruits and vegetables was lower, among food insecure than secure participants. Food insecurity was positively related to overweight and obesity (odds ratio: 2.66; confidence interval: 1.25-5.69; P < .01).Conclusions and ImplicationsSomali refugees experienced high levels of food insecurity upon resettlement. Poor dietary habits and the high overweight/obesity rate among insecure families call for future research in understanding what role family structure, cultural norms, and food preference play in predicting food security and dietary habits among Somali and overall African refugees in the United States.     

Dietary factors and body mass index in a group of Iranian adolescents: Tehran lipid and glucose study--2

OBJECTIVE: To study the prevalence of overweight and obesity in an adolescent population in Tehran and to determine possible association with energy and nutrient intake and distribution of energy over the day. METHOD: A cross-sectional study on 177 boys and 244 girls between 10-19 years old was performed. Overweight and obesity were defined by using recommended body mass index (BMI) cut-off values for adolescents. Total energy intake, percent of energy derived from protein, carbohydrate and fat and percent of energy supplied by each meal and snack were assessed by means of two 24-hour dietary recalls. RESULTS: Prevalence of overweight and obesity was 10.7 and 5.1 in boys and 18.4 and 2.8 in girls, respectively. The composition of diet was not different between overweight/obese and normal weight subjects. BMI was related with breakfast energy percentage in girls (r = -0.18, p < 0.01), with total energy intake in boys (r = 0.23, p < 0.01), and with lunch energy percentage in both sexes. In boys (r = 0.16, p < 0.05) and in girls (r = 0.22, p < 0.01). CONCLUSION: High prevalence of overweight and obesity among adolescents was seen. In boys some relationship between total energy intake, distribution of energy over the day and BMI was seen. In girls BMI was only related with distribution of energy over the day.     

The Contribution of Snacking to Overall Diet Intake among an Ethnically and Racially Diverse Population of Boys and Girls

BackgroundChildren in low-income and minority populations are at risk for poor dietary quality. At least one-third of the calories consumed by children are eaten between meals (ie, snacks). The contribution of snacking to diet quality among children is poorly understood.ObjectiveThe current study examined associations between snacking and children’s diet quality along with differences across ethnicity or race, sex, and weight status.DesignCross-sectional data came from Phase I of the Family Matters Study, an observational study.Participants/settingThis study included 150 families with children aged 5 to 7 years old from six ethnic or racial groups (n=25 from each: African American, Hispanic, Hmong, Native American, Somali, non-Hispanic white); data were collected in Minneapolis–Saint Paul, MN in 2017-2018.Main outcome measuresTotal daily energy (kilocalories), overall diet quality using the Healthy Eating Index (HEI-2010), and food group intakes (eg, fruit, vegetables, refined grains, sugar-sweetened beverages [SSB]) were assessed using three 24-hour dietary recalls.Statistical analyses performedConditional fixed effects estimators (within-child variation) were used in regression analyses to characterize the relationship between daily snacking and dietary intake relative to dietary intake at all other daily meal occasions. Mean (±standard deviation) overall dietary intake including all meals and snacks was compared with mean (±standard deviation) intake of meals only.ResultsAmong boys, snacking was found to contribute positively to HEI-2010 scores (HEI-2010=57.6, HEI-2010 without snacks=55.0; effect size [ES]=0.28, P=0.03). Snacking was an important source of fruit (ES=0.71) and dairy (ES=0.53), but also contributed to children’s consumption of refined grains (ES=0.68) and SSB (ES=0.31). Very few vegetables were consumed as snacks. Furthermore, snacks contributed more to the overall diet quality (HEI-2010) of Native American (ES=0.30) and Somali (ES=0.35) youth as compared with youth from other ethnic or racial backgrounds.ConclusionsFindings suggest that snacks have the potential to improve diet quality in children. Future research should examine influences on children’s food choices at snack times and barriers to serving more healthful foods as snacks that are faced by ethnically or racially diverse families.     

Food intake among children under three years of age in an area with high food insecurity

This study focused on the association between food insecurity and children's dietary intake in a representative sample of children in an area with high food insecurity in Duque de Caxias, Rio de Janeiro State, Brazil. This was a cross-sectional, population-based study with a probabilistic cluster sample of 402 families with children ranging from six to 30 months of age. Food insecurity was assessed based on the Brazilian Food Insecurity Scale (EBIA), and children's dietary intake was evaluated with two 24-hour recalls. Intake levels for food groups, energy, and nutrients were compared according to food insecurity status. Intake of sugar/sweets and fat was high, regardless of food insecurity status, and coffee intake was significantly higher among children with food insecurity. In the energy-adjusted linear regression model, protein intake was inversely associated with the EBIA (p = 0.005). The results suggest that family food insecurity jeopardizes the quality of children's diet, reducing the consumption of protein and increasing the consumption of coffee and high energy density foods.     

Twenty-four hour dietary recalls by fourth-grade children were not influenced by observations of school meals

ObjectiveTo investigate whether school-meal observations influenced children's 24-hour dietary recalls.Study Design and SettingOver three school years, 555 randomly selected fourth-grade children were interviewed to obtain a 24-hour dietary recall; before being interviewed, 374 children were observed eating two school meals (breakfast, lunch), and 181 children were not observed. Within observation-status groups (observed, unobserved), children were randomized within sex to one of six combinations from two target periods (prior 24 hours, previous day) crossed with three interview times (morning, afternoon, evening).ResultsFor each of the five variables (interview length, meals/snacks, meal components, items, kilocalories), naïve and adjusted equivalence tests rejected that observation-status groups were different, indicating that school-meal observations did not influence children's 24-hour dietary recalls. There was a target-period effect on length (P < 0.0001) (longer for prior-24-hour recalls), a school year effect on length (P = 0.0002) (longer for third year), and a target period–interview time interaction on items (P = 0.0110) and kilocalories (P = 0.0047) (both smaller for previous-day recalls in the afternoon than prior-24-hour recalls in the afternoon and previous-day recalls in the evening), indicating that variables were sufficiently sensitive and psychometrically reliable.ConclusionConclusions about 24-hour dietary recalls by fourth-grade children observed eating school meals in validation studies are generalizable to 24-hour dietary recalls by comparable but unobserved children in nonvalidation studies.     

Dietary Associations of Household Food Insecurity among Children of Mexican Descent: Results of a Binational Study

Background/objectiveChildren of Mexican descent frequently experience household food insecurity both in the United States and Mexico. However, little is known about the associations of food insecurity with dietary intake. This study aimed to understand the level of perceived food insecurity and its association with dietary intake among children of Mexican descent residing in the United States and Mexico.DesignThis cross-sectional study utilized data from a 2006 binational study of 5-year-old children of Mexican descent living in migrant communities in California and Mexico.MethodsIn California, children were 301 participants from the Center for the Health Assessment of Mothers and Children of Salinas study, a longitudinal birth cohort in a Mexican immigrant community. Mexican children (n=301) were participants in the Proyecto Mariposa study, which was designed to capture a sample of women and their children living in Mexico who closely resembled the California sample, yet who never migrated to the United States. Household food insecurity was measured using the US Department of Agriculture Food Security Scale and dietary intake was assessed with food frequency questionnaires. Analysis of variance was used to examine unadjusted and adjusted differences in total energy, nutrient intake, and consumption of food groups by household food security status.ResultsApproximately 39% of California mothers and 75% of Mexico mothers reported low or very low food security in the past 12 months (P<0.01). Children in the United States experiencing food insecurity consumed more fat, saturated fat, sweets, and fried snacks than children not experiencing food insecurity. In contrast, in Mexico food insecurity was associated with lower intake of total carbohydrates, dairy, and vitamin B-6.ConclusionsPrograms and policies addressing food insecurity in the United States and Mexico may need to take steps to address dietary intake among children in households experiencing food insecurity, possibly through education and programs to increase resources to obtain healthful foods.     

Dietary sugar intake and dietary behaviors in Korea: a pooled study of 2,599 children and adolescents aged 9-14 years

BACKGROUND/OBJECTIVESDietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents.SUBJECTS/METHODSWe pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records.RESULTSMean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls).CONCLUSIONSThese results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

Evaluating a Food Pantry–Based Intervention to Improve Food Security,Dietary Intake,and Quality in Midwestern Food Pantries

BackgroundVoices for Food was a longitudinal community, food pantry–based intervention informed by the social ecological model, and designed to improve food security, dietary intake, and quality among clients, which was carried out in 24 rural food pantries across 6 Midwestern states.ObjectiveOur objective was to evaluate changes in adult food security, dietary intake, and quality from baseline (2014) to follow-up (2016), and to assess the role of adult food security on dietary outcomes.DesignA multistate, longitudinal, quasi-experimental intervention with matched treatment and comparison design was used to evaluate treatment vs comparison group changes over time and changes in both groups over time.Participants/settingAdult food pantry clients (n = 617) completed a demographic food security survey, and up to three 24-hour dietary recalls at baseline (n = 590) and follow-up (n = 160).InterventionCommunity coaching served as the experimental component, which only “treatment” communities received, and a food council guide and food pantry toolkit were provided to both “treatment” and matched “comparison” communities.Main outcome measuresChange in adult food security status, mean usual intakes of nutrients and food groups, and Healthy Eating Index-2010 scores were the main outcome measures.Statistical analyses performedLinear mixed models estimated changes in outcomes by intervention group and by adult food security status over time.ResultsImprovements in adult food security score (–0.7 ± 0.3; P = .01), Healthy Eating Index-2010 total score (4.2 ± 1.1; P < .0001), and empty calories component score (3.4 ± 0.5; P <.0001) from baseline to follow-up were observed in treatment and comparison groups, but no statistically significant changes were found for adult food security status, dietary quality, and usual intakes of nutrients and food groups between the 2 groups over time. The intervention effect on dietary quality and usual intake changes over time by adult food security status were also not observed.ConclusionsFood pantry clients in treatment and comparison groups had higher food security and dietary quality at the follow-up evaluation of the Voices for Food intervention trial compared with baseline, despite the lack of difference among the groups as a result of the experimental coaching component.     

Parent–Child Associations in Selected Food Group and Nutrient Intakes among Overweight and Obese Adolescents

Few studies have compared parent–child dietary intake among adolescents who are overweight or obese. The purpose of our study was to determine the relationship between parent–teen intake of selected dietary components among this sample. Baseline data from 165 parent and adolescent (aged 11 to 16 years) pairs who presented for a lifestyle behavior modification intervention were collected between 2010 and 2012. Parent and adolescent dietary intake (servings of fruits and vegetables [F/V]; grams of sugar; and percent energy from total fat, saturated fat, dessert/treats, sugar-sweetened beverages, and snacks) was assessed using web-based 24-hour dietary recalls. Multivariable linear and negative binomial regression models identified associations between parent and child dietary intake adjusting for relevant covariates. A large proportion of adolescents and parents did not meet dietary recommendations for F/V, total fat, and saturated fat. Parent–adolescent intake of F/V, total fat, saturated fat, sugar, sugar-sweetened beverages, and snacks were positively associated (r=0.19 to 0.37). No relationship was observed for dessert/treats. In multivariate models, significant interaction effects suggest that the parent–child association in diet was weaker for fat intake among parents with higher educational attainment (b=–.31; P<0.05) and for snacking among adolescent boys (b=–.30; P<.05). Parent intake of several dietary components important for good health, and related to obesity, was associated with adolescent intake. Helping parents improve their diet may promote improvements in their adolescent's diet and is a potential target for interventions designed to increase healthy eating among adolescents.     

24-Hour dietary recall in patients with bulimia nervosa

The accuracy of 24-hour dietary recall of patients with bulimia nervosa was examined by comparing the actual intake of subjects in a laboratory meal with their reported intake in a 24-hour dietary recall interview. The mean caloric intake of the 15 patients who participated in the study was 1,088 (SD 1,335) kilocalories. There were significant positive correlations between actual and recalled kilocalories (r² = .97, p < .001), total grams (r² = .92, p < .001), and grams of macronutrients consumed (protein r² = .96; fat r² = .97; carbohydrate r2 = .94; p < .001). However, there was a tendency for patients to overestimate the amount of food they had eaten when actual intake was large.     

Food Insecurity and Dietary Intake among College Students with Unlimited Meal Plans at a Large,Midwestern University

BackgroundFood insecurity, a state of not being able to consistently access nutritious food due to financial constraints, has been associated with poor dietary intake among college students. The extent to which campus food resources contribute to this association is unknown.ObjectivesThis study examined the association between food insecurity and dietary intake in a sample of undergraduate students with unlimited meal plans and dining hall access at a large, public Midwestern university.DesignThe study design is cross-sectional. The data used are baseline data from a broader sugar-sweetened beverage intervention study that were collected using a Qualtrics survey prior to the intervention.Participants/settingThe sample consisted of 1033 undergraduate students recruited from 3 dining halls. The data were collected in November 2018.Main outcome measuresFood security was assessed using the 6-item Short Form Food Security Survey Module. Dietary intake was assessed using the National Cancer Institute 26-item Dietary Screener Questionnaire and the Beverage Intake Questionnaire-15.Statistical analyses performedGeneralized linear regression models were used to examine differences in dietary intake by students’ food security status, adjusting for students’ sociodemographic characteristics.ResultsIn the sample, 14% of students were food-insecure. After adjusting for sociodemographic variables, food-insecure students reported 9% lower intake of fruits (P = 0.02), 9% lower intake of vegetables (P < 0.001), 10% higher intake of dairy (P = 0.002), 6% higher intake of total added sugars (P = 0.01), 10% higher intake of added sugars from sugar-sweetened beverages (P = 0.01), 4% higher intake of calcium (P = 0.01), and 4% lower intake of fiber (P = 0.01) compared with food-secure students. With respect to beverage intake, food-insecure students had 56% higher intake of total sugar-sweetened beverages (P = 0.002), which was driven by 185% higher intake of energy and sports drinks (P = 0.001), and 121% higher intake of sweetened teas (P = 0.001).ConclusionsDespite having identical food resources within campus dining halls, there were significant differences in the diets of college students by food security status.     

Food and nutrient intakes of a population sample of 7-year-old children in the south-west of England in 1999/2000 – what difference does gender make?

Objectives To describe the diet of schoolchildren aged 7 years, and identify gender differences in food and nutrient intakes. Subjects A cohort of children resident in the south-west of England in 1999/2000. Methods Diet was assessed using three 1-day unweighed food diaries. Nutrient intakes were compared with dietary reference values for this age group, and with children aged 7–10 years in the British National Diet and Nutrition Survey. Food and nutrient intakes were contrasted between boys and girls. Results Median nutrient intakes exceeded the reference nutrient intake (RNI) for most nutrients. Median intakes of iron and zinc were below the RNI. Median sodium intake was greater than the maximum set by the Scientific Advisory Committee on Nutrition. The mean energy intake for boys and girls, respectively, were 7.3 and 6.8 MJ, this is below the estimated average requirement. The percentage of energy from fat was 35.3% for boys and 36.1% for girls. Boys had higher iron intakes than girls, even after adjustment for energy intake. There were differences in the types of foods eaten between boys and girls; girls ate more fruit and vegetables (P = 0.001) and boys ate more breakfast cereals (P = 0.016). Conclusions The dietary intakes of these 7-year-old children were adequate for most nutrients. However, a reduction in the sodium content of the diet would be advantageous. Fruit and vegetable consumption should be encouraged particularly among boys.     

The National Cancer Institute diet history questionnaire: validation of pyramid food servings

The performance of the National Cancer Institute's food frequency questionnaire, the Diet History Questionnaire (DHQ), in estimating servings of 30 US Department of Agriculture Food Guide Pyramid food groups was evaluated in the Eating at America's Table Study (1997-1998), a nationally representative sample of men and women aged 20-79 years. Participants who completed four nonconsecutive, telephone-administered 24-hour dietary recalls (n = 1,301) were mailed a DHQ; 965 respondents completed both the 24-hour dietary recalls and the DHQ. The US Department of Agriculture's Pyramid Servings Database was used to estimate intakes of pyramid servings for both diet assessment tools. The correlation (rho) between DHQ-reported intake and true intake and the attenuation factor (lambda) were estimated using a measurement error model with repeat 24-hour dietary recalls as the reference instrument. Correlations for energy-adjusted pyramid servings of foods ranged from 0.43 (other starchy vegetables) to 0.84 (milk) among women and from 0.42 (eggs) to 0.80 (total dairy food) among men. The mean rho and lambda after energy adjustment were 0.62 and 0.60 for women and 0.63 and 0.66 for men, respectively. This food frequency questionnaire validation study of foods measured in pyramid servings allowed for a measure of food intake consistent with national dietary guidance.     

Diet of children under the government-funded meal support program in Korea

The purpose of this study was to investigate the diet of children under the government-funded meal support program. The 143 children (67 boys and 76 girls) participated in this study among 4^th-6^th elementary school students receiving free lunches during the summer vacation of 2007 and living in Gwanak-gu, Seoul, Korea. The subjects consisted of four groups supported by Meal Box Delivery (n = 26), Institutional Foodservice (n = 53), Restaurant Foodservice (n = 27), or Food Delivery (n = 37). A three-day 24-hour dietary recall and a self-administered survey were conducted. In addition, the children''s heights and weights were measured. The average energy intake of the children was 1,400 kcal per day, much lower than the Estimated Energy Requirements of the pertinent age groups. The results also showed inadequate intake of all examined nutrients; of particular concern was the extremely low intake of calcium. On average, the children consumed eight dishes and 25 food items per day. The children supported by Meal Box Delivery consumed more various dishes and food items than the other groups. The percentage of children preferring their current meal support method was the highest in those supported by Meal Box Delivery and the lowest in those supported by Food Delivery. We requested 15 children among the 143 children participating in the survey to draw the scene of their lunch time. The drawings of the children supported by Institutional Foodservice showed more positive scenes than the other groups, especially in terms of human aspects. In conclusion, the overall diet of children under the government-funded meal support program was nutritionally inadequate, although the magnitude of the problems tended to differ by the meal support method. The results could be utilized as basic data for policy and programs regarding the government-funded meal support program for children from low-income families.     

Dietary fiber and fat are associated with excess weight in young and middle-aged US adults

OBJECTIVE: To examine relative associations of dietary composition variables with body mass index (BMI; calculated as kg/m2) among young and middle-aged US adults. We hypothesized that in subjects with physiologically plausible reported energy intakes, fiber intake would be inversely associated with BMI, independent of other dietary composition and sociodemographic variables. SUBJECTS AND DESIGN: Data from adults age 20 to 59 years in the Continuing Survey of Food Intakes by Individuals (CSFII) 1994-1996 were used. Exclusions were pregnancy or lactation, food insecurity, missing weight or height data, or having only one dietary recall. Based on our previously published methods, a physiologically plausible reported energy intake was calculated as being within +/-22% of predicted energy requirements for the mean of two 24-hour recalls. RESULTS: Reporting plausibility ([reported energy intake/predicted energy requirements]x100) averaged 83% in the total sample (N=4,539) and increased to 96% in the plausible sample (n=1,932). Only approximately 5% of the plausible sample consumed the Adequate Intake for fiber. In plausibly reporting women, fiber, its interaction with percentage energy from fat, and energy density were independently associated with BMI. Only percentage energy from fat was associated with BMI in men reporting plausibly. Compared with the total sample, stronger relationships between diet and BMI were observed among the plausible reporters. In women, a low-fiber (< 1.5 g/MJ), high-fat (> or = 35% energy) diet was associated with the greatest increase in risk of overweight or obesity compared with a high-fiber, low-fat diet. CONCLUSIONS: Weight control advice for US women should place greater emphasis on consumption of fiber.
