Race/ethnicity and income in relation to the home food environment in US youth aged 6 to 19 years.

BACKGROUND: The home food environment is complex and has the potential to influence dietary habit development in young people. Several factors may influence the home food environment, including income and race/ethnicity. OBJECTIVE: To examine the relationship of income and race/ethnicity with three home food environment factors (ie, food availability frequency, family meal patterns [frequency of family and home cooked meals], and family food expenditures). DESIGN: A cross-sectional analysis of the National Health and Nutrition Examination Survey (NHANES). PARTICIPANTS: A total of 5,096 youth aged 6 to 19 years from a nationally representative sample of US individuals participating in NHANES 2007-10. STATISTICAL ANALYSES PERFORMED: Prevalence of food availability frequency was assessed for the entire sample, race/ethnicity, poverty income ratio (PIR), and race/ethnicity stratified by PIR. Mean values of family meal patterns and food expenditures were calculated based on race/ethnicity, PIR, and race/ethnicity stratified by PIR using analysis of variance and least squares means. Tests of main effects were used to assess differences in food availability prevalence and mean values of family meal patterns and food expenditures. RESULTS: Non-Hispanic whites had the highest prevalence of salty snacks (51.1%±1.5%) and fat-free/low-fat milk (39.2%±1.7%) always available. High-income homes had the highest prevalence of fruits (75.4%±2.4%) and fat-free/low-fat milk (38.4%±2.1%) always available. Differences were found for prevalence of food availability when race/ethnicity was stratified by PIR. Non-Hispanic blacks had the lowest prevalence of fat-free/low-fat milk always available across PIR groups. Differences in mean levels of family meal patterns and food expenditures were found for race/ethnicity, PIR, and race/ethnicity stratified by PIR. CONCLUSIONS: Race/ethnicity and PIR appear to influence food availability, family meal patterns, and family food expenditures in homes of youth. Knowledge of factors that influence the home food environment could assist in developing effective strategies to improve food environments for young people.

Correlation of omega-3 fatty acids intakes with acculturation and socioeconomic status in midwestern Latinas.

BACKGROUND: Low socioeconomic status (SES) and acculturation of Latino immigrants in the U.S. are linked to a decrease in diet quality. METHODS: Interviews were conducted with 162 first generation Latinas to examine the association of SES and acculturation with intake of omega-3 (n - 3) fatty acids. Each participant provided dietary intake by use of a validated n - 3 food frequency questionnaire administered twice, 4 weeks apart, three 24-h recalls, sociodemographic information and completed the 5-item Short Acculturation Scale. RESULTS: Mean intakes of Total n - 3, α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (g/d) were 1.2 ± 0.7, 1.1 ± 0.6, and 0.1 ± 0.1, respectively. After adjusting for energy intake, education was significantly correlated with EPA + DHA intakes, and acculturation was significantly correlated with Total n - 3, ALA and EPA + DHA intakes. Foods sources of EPA + DHA eaten by at least 50% of participants were chicken, shrimp, tuna and eggs. DISCUSSION: Given the beneficial cardiovascular effects of n - 3 fatty acids, it is important to understand sociocultural factors affecting adequate intake towards an improvement in diet quality in minorities.

Personal food systems of male collegiate football players: a grounded theory investigation.

CONTEXT: Factors that affect food choices include the physical and social environments, quality, quantity, perceived healthfulness, and convenience. The personal food choice process was defined as the procedures used by athletes for making food choices, including the weighing and balancing of activities of daily life, physical well-being, convenience, monetary resources, and social relationships. OBJECTIVE: To develop a theoretical model explaining the personal food choice processes of collegiate football players. DESIGN: Qualitative study. SETTING: National Collegiate Athletic Association Division II football program. PATIENTS OR OTHER PARTICIPANTS: Fifteen football players were purposefully sampled to represent various positions, years of athletic eligibility, and ethnic backgrounds. DATA COLLECTION AND ANALYSIS: For text data collection, we used predetermined, open-ended questions. Data were analyzed using the constant comparison method. The athletes' words were used to label and describe their interactions and experiences with the food choice process. Member checks and an external audit were conducted by a qualitative methodologist and a nutrition specialist, and the findings were triangulated with the current literature to ensure trustworthiness of the text data. RESULTS: Time was the core category and yielded a cyclic graphic of a theoretical model for the food choice system. Planning hydration, macronutrient strategies, snacks, and healthful food choices emerged as themes. CONCLUSIONS: The athletes planned meals and snacks around their academic and athletic schedules while attempting to consume foods identified as healthful. Healthful foods were generally lower in fat but high in preferred macronutrients. High-protein foods were the players' primary goal; carbohydrate consumption was secondary. The athletes had established plans to maintain hydration. Professionals may use these findings to implement educational programs on food choices for football players.

Validity and reliability of an omega-3 fatty acid food frequency questionnaire for first-generation Midwestern Latinas.

This study tested the hypothesis that a culturally developed omega-3 (n-3) fatty acid food frequency questionnaire (FFQ) could be an accurate instrument to capture n-3 fatty acid food intakes of first-generation Midwestern Latinas. The goal of the study was to assess validity and test-retest reliability of an FFQ to estimate total n-3 fatty acid (total n-3), α-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) intakes. An n-3 FFQ was developed and pilot tested. Two FFQs and 3 nonconsecutive 24-hour recalls were collected from 162 participants. Pearson correlation and paired t test were used to test the hypothesis. Correlation of the 2 FFQs was 0.71 for total n-3, 0.65 for ALA, 0.74 for EPA, and 0.54 for DHA (P < .01). The means of the 2 FFQs and of the 24-hour recalls were not significantly different for total n-3 and ALA (P > .05), but were significantly different for EPA and DHA. The n-3 FFQ had acceptable reliability, validated only total n-3 and ALA, and provided relevant findings about the n-3 eating habits of Midwestern Latinas.
