Using Behavioral Risk Factor Surveillance System Data to Estimate the Percentage of the Population Meeting US Department of Agriculture Food Patterns Fruit and Vegetable Intake Recommendations.

Most Americans do not eat enough fruits and vegetables with significant variation by state. State-level self-reported frequency of fruit and vegetable consumption is available from the Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System (BRFSS). However, BRFSS cannot be used to directly compare states' progress toward national goals because of incongruence in units used to measure intake and because distributions from frequency data are not reflective of usual intake. To help states track progress, we developed scoring algorithms from external data and applied them to BRFSS 2011 data to estimate the percentage of each state's adult population meeting US Department of Agriculture Food Patterns fruit and vegetable intake recommendations. We used 24-hour dietary recall data from the National Health and Nutrition Examination Survey, 2007-2010, to fit sex- and age-specific models that estimate probabilities of meeting recommendations as functions of reported consumption frequency, race/ethnicity, and poverty-income ratio adjusting for intraindividual variation. Regression parameters derived from these models were applied to BRFSS to estimate the percentage meeting recommendations. We estimate that 7%-18% of state populations met fruit recommendations and 5%-12% met vegetable recommendations. Our method provides a new tool for states to track progress toward meeting dietary recommendations.

The Association of Meal Practices and Other Dietary Correlates With Dietary Intake Among High School Students in the United States, 2010.

PURPOSE: To examine behavioral and environmental factors that may be related to dietary behaviors among U.S. high school students. DESIGN: Data were obtained from the 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. SETTING: The study was school-based. SUBJECTS: Study subjects were a nationally representative sample of students in grades 9 to 12 (n = 11,458). MEASURES: Variables of interest included meal practices, in-home snack availability, and intakes of healthful foods/beverages (fruits, vegetables, water, and milk) and less healthful foods/beverages (fried potatoes, pizza, and sugar-sweetened beverages). ANALYSIS: Sex-stratified logistic regression models were used to examine associations of meal practices and snack availability with dietary intake. Odds ratios (ORs) were adjusted for race/ethnicity and grade. RESULTS: Eating breakfast daily, frequent family dinners, and bringing lunch from home were associated with higher odds of consuming at least three healthful foods or beverages. High fast-food intake was associated with lower odds of healthful dietary intake and higher odds of sugar-sweetened beverage intake (female OR = 3.73, male OR = 4.60). Students who mostly/always had fruits and vegetables available at home had increased odds of fruits (female OR = 3.04, male OR = 2.24), vegetables (female OR = 2.12, male OR = 1.65), water (female OR = 1.82, male OR = 1.85), and milk intake (female OR = 1.45, male OR = 1.64). CONCLUSION: Encouraging daily breakfast consumption, frequent family dinners, and fruit and vegetable availability at home may lead to higher intakes of healthful foods among high school students.

Fruit and vegetable intake during infancy and early childhood.

OBJECTIVES: To examine the association of timing of introduction and frequency of fruit and vegetable intake during infancy with frequency of fruit and vegetable intake at age 6 years in a cohort of US children. METHODS: We analyzed data on fruit and vegetable intake during late infancy, age of fruit and vegetable introduction, and frequency of fruit and vegetable intake at 6 years from the Infant Feeding Practices Study II and the Year 6 Follow-Up (Y6FU) Study. We determined the percent of 6-year-old children consuming fruits and vegetables less than once per day and examined associations with infant fruit and vegetable intake using logistic regression modeling, controlling for multiple covariates (n = 1078). RESULTS: Based on maternal report, 31.9% of 6-year-old children consumed fruit less than once daily and 19.0% consumed vegetables less than once daily. In adjusted analyses, children who consumed fruits and vegetables less than once daily during late infancy had increased odds of eating fruits and vegetables less than once daily at age 6 years (fruit, adjusted odds ratio: 2.48; vegetables, adjusted odds ratio: 2.40). Age of introduction of fruits and vegetables was not associated with intake at age 6 years. CONCLUSIONS: Our study suggests that infrequent intake of fruits and vegetables during late infancy is associated with infrequent intake of these foods at 6 years of age. These findings highlight the importance of infant feeding guidance that encourages intake of fruits and vegetables and the need to examine barriers to fruit and vegetable intake during infancy.

Access to healthier food retailers - United States, 2011.

According to the Dietary Guidelines for Americans, persons in the United States aged ≥2 years should increase their intake of certain nutrient-rich foods, including fruits and vegetables. Fruits and vegetables contribute important nutrients that are underconsumed in the United States. Higher intake of fruits and vegetables might reduce the risk for many chronic diseases including heart disease, stroke, diabetes, and some types of cancer. In addition, replacing high-calorie foods with fruits and vegetables can aid in weight management. However, most persons in the United States do not consume the recommended amounts of fruits and vegetables and other healthier food groups (e.g., whole grains or fat-free or low-fat dairy foods).

Household income disparities in fruit and vegetable consumption by state and territory: results of the 2009 Behavioral Risk Factor Surveillance System.

Few studies take into account the influence of family size on household resources when assessing income disparities in fruit and vegetable (F/V) consumption. Poverty income ratio (PIR) is a measure that utilizes both reported income and household size. We sought to examine state-specific disparities in meeting Healthy People 2010 objectives for F/V consumption by percent PIR. This analysis included 353,005 adults in 54 states and territories reporting data to the 2009 Behavioral Risk Factor Surveillance System in the United States. Percent PIR was calculated using the midpoint of self-reported income range and family size. The prevalences consuming at least two fruits and at least three vegetables per day were examined by percent PIR (<130% [greatest poverty], 130% to <200%, 200% to <400%, and ≥ 400% [least poverty]). The percent of adults consuming vegetables at least three times daily was significantly lower (21.3%) among those living at greatest poverty (<130% PIR) compared with 30.7% among those with least poverty (≥ 400% PIR). Daily consumption of vegetables at least three times was significantly lower among those with greatest poverty in a majority of states and territories surveyed (43 of 54). The overall percent of adults consuming fruits at least 2 times daily was also lower among those living at greatest vs least poverty, but the difference was smaller (32.0% vs 34.2%), with 14 states reporting a difference that was significantly lower among those with greatest poverty. Our study revealed that in 2009 a significantly lower proportion of US adults living at greatest poverty consumed fruits at least two times daily or vegetables at least three times daily compared with those with the least poverty, with greater disparity in vegetable intake. Policy and environmental strategies for increased affordability, access, availability, and point-of-decision information are approaches that may help disparate households purchase and consume F/V.

Iron-fortified wheat flour and iron deficiency among women.

BACKGROUND: Iron deficiency is estimated to impact more than 1.6 billion individuals worldwide, affecting child, maternal, and perinatal mortality. Iron supplementation, fortification, and dietary diversification are strategies to reduce the prevalence of iron deficiency. However, there are relatively few studies demonstrating the effectiveness of iron-fortified wheat flour as an intervention. OBJECTIVE: To assess the relationship between average monthly per capita household consumption of iron-fortified wheat flour and iron deficiency among women of childbearing age in Oman. METHODS: Data were obtained from the National Micronutrient Status and Fortified Food Coverage Survey, 2004. Iron deficiency status was compared between women living in households with a monthly per capita consumption of iron-fortified wheat flour of 1 kg or more and women living in households with a monthly per capita consumption of iron-fortified wheat flour of less than 1 kg. The analyses excluded women with elevated or unknown levels of C-reactive protein and controlled for characteristics of the women and household demographics. RESULTS: Consumption of iron-fortified wheat flour was associated with a lower prevalence of iron deficiency among women in our sample (adjusted odds ratio, 0.60), after controlling for age, employment status, marital status, intake of iron or multivitamin supplements, self-reported presence of a blood disorder, household income, educational level of head of household, and family size. CONCLUSIONS: These results suggest that women in our study living in households with a greater consumption of iron-fortified wheat flour have a lower prevalence of iron deficiency; however, additional study is needed.

Strategies for pediatric practitioners to increase fruit and vegetable consumption in children.

High intake of fruits and vegetables (FV) is associated with a decreased risk for many chronic diseases and may assist in weight management, but few children and adolescents consume the recommended amounts of FV. The pediatric practitioner can positively influence FV consumption of children through patient-level interventions (eg, counseling, connecting families to community resources), community-level interventions (eg, advocacy, community involvement), and health care facility-level interventions (eg, creating a healthy food environment in the clinical setting). This article reviews the importance of FV consumption, recommended intakes for children, and strategies by which pediatric practitioners can influence FV consumption of children.
