ABSTRACT To examine how factors related to the home food environment and individual characteristics are associated with healthy food purchasing among low-income African American (AA) youth.
A total of 206 AA youth (ninety-one boys and 115 girls), aged 10-14 years, and their primary adult caregivers.
Fourteen Baltimore recreation centres in low-income neighbourhoods.
Cross-sectional study. We collected information about food purchasing, the home food environment, sociodemographic and psychosocial factors drawn from social cognitive theory. Multivariable logistic regression was used to examine the factors associated with the frequency and proportion of healthy food purchases in all youth and stratified by gender. Low-fat or low-sugar foods were defined as healthy.
Youth purchased an average of 1.5 healthy foods (range=0-15) in the week before the interview, comprising an average of 11.6% (range=0-80%) of total food purchases. The most commonly purchased healthy foods included water and sunflower seeds/nuts. Healthier food-related behavioural intentions were associated with a higher frequency of healthy foods purchased (OR=1.4, P<0.05), which was stronger in girls (OR=1.9, P<0.01). Greater caregiver self-efficacy for healthy food purchasing/preparation was associated with increased frequency of healthy purchasing among girls (OR=1.3, P<0.05). Among girls, more frequent food preparation by a family member (OR=6.6, P<0.01) was associated with purchasing a higher proportion of healthy foods. No significant associations were observed for boys.
Interventions focused on AA girls should emphasize increasing food-related behavioural intentions. For girls, associations between caregiver self-efficacy and home food preparation suggest the importance of the caregiver in healthy food purchasing.

    ABSTRACT: Examine intentions to buy and eat dark green leafy vegetables (DGLV). Cross-sectional survey assessing demographics, behavior, intention, and Reasoned Action Approach constructs (attitude, perceived norm, self-efficacy). Marion County, Indiana. African American women responsible for buying and preparing household food. Reasoned Action Approach constructs explaining intentions to buy and eat DGLV. Summary statistics, Pearson correlations, and multiple regression analyses. Among participants (n = 410, mean age = 43 y), 76% and 80%, respectively, reported buying and eating DGLV in the past week. Mean consumption was 1.5 cups in the past 3 days. Intentions to buy (r = 0.20, P < .001) and eat (r = 0.23, P < .001) DGLV were positively associated with consumption. Reasoned Action Approach constructs explained 71.2% of the variance in intention to buy, and 60.9% of the variance in intention to eat DGLV. Attitude (β = .63) and self-efficacy (β = .24) related to buying and attitude (β = .60) and self-efficacy (β = .23) related to eating DGLV explained significant amounts of variance in intentions to buy and eat more DGLV. Perceived norm was unrelated to either intention to buy or eat DGLV. Interventions designed for this population of women should aim to improve DGLV-related attitudes and self-efficacy.

    ABSTRACT: Obesity disproportionately affects African American (AA) children and adolescents and leads to an increased risk of adult chronic diseases. Eating few meals at home has been implicated as a cause of obesity among youth, but to our knowledge, previous studies have not specifically investigated this relationship in AA adolescents or looked at both the healthfulness and frequency of home meals in AA households. The objective of the present study was to investigate the relationship between home food preparation and adolescent BMI in a sample of 240 AA adolescents aged 10-15 y and their caregivers. Multiple linear regressions were used to model psychosocial characteristics, household factors, and adolescent and caregiver food preparation behaviors as predictors of adolescent BMI, and psychosocial and household factors as predictors of food preparation behavior. Adolescents in the sample had a mean BMI-for-age percentile of 70.4, and >90% of the sample families received at least one form of food assistance. Adolescent children of caregivers who used healthier cooking methods were more likely to use healthy cooking methods themselves (P = 0.02). Having more meals prepared by a caregiver was predictive of higher BMI-for-age percentile in adolescents (P = 0.02), but healthier cooking methods used by the caregiver was associated with reduced risk of adolescent overweight or obesity (P < 0.01). Meals prepared at home in AA households do not necessarily promote healthy BMI in youth. Family meals are a promising adolescent obesity prevention strategy, but it is important to target both frequency and healthfulness of meals prepared at home for effective health promotion in AA families.

    ABSTRACT: To understand environmental factors influencing the food-related habits of low-income urban African American adolescents. Qualitative research was conducted between February and April, 2010, using in-depth interviews, focus groups, and direct observation. The study was conducted in low-income, predominantly African American neighborhoods of Baltimore City. A total of 20 adolescents were interviewed in 18 in-depth interviews (n = 13) and 2 focus groups (n = 7). Participants were recruited from Baltimore City recreation centers and were eligible if they were African American and aged 10-16 years. The food-related habits of low-income, African American, urban adolescents and reported perceptions of their food environments. Interviews were audio recorded, transcribed, coded, and analyzed for emerging themes. Six thematic categories emerged and were organized into 4 environmental contexts: the neighborhood context (accessibility of food and safety of neighborhood), the school context (school food environment), the family context (family health history, role modeling, and monitoring) and the peer context (peer behaviors). Future efforts to reduce the obesity epidemic among low-income African American adolescents should address the social environment of the family; however, positive behavior change may not be sustainable without neighborhood or school food environment modifications.
