The consumption of sugar-sweetened beverages has been linked to risks for obesity, diabetes, and heart disease 1-3 ; therefore, a compelling case can be made for the need for reduced consumption of these beverages. Sugar-sweetened beverages are beverages that contain added, naturally derived caloric sweeteners such as sucrose (table sugar), high-fructose(More)
We examine whether neighborhood alcohol outlet density is associated with reduced social capital and whether this relationship is mediated by perceived neighborhood safety. Hierarchical models from a random sample of Los Angeles, CA, and Louisiana residents (N=2,881) from 217 census tracts were utilized. Substantial proportions of the variance in collective(More)
BACKGROUND Behavior is influenced by individual-level attributes as well as by the conditions under which people live. Altering policies, practices, and the conditions of life can directly and indirectly influence individual behavior. This paper builds on existing ecological theories of health behavior by specifying structural mechanisms by which(More)

OBJECTIVE Previous studies on the relationship of dietary intake to the neighbourhood food environment have focused on access to supermarkets, quantified by geographic distance or store concentration measures. However, in-store food availability may also be an important determinant, particularly for urban neighbourhoods with a greater concentration of small(More)
Dietary patterns may be influenced by the availability and accessibility within stores of different types of foods. However, little is known about the amount of shelf space used for healthy and unhealthy foods in different types of stores. We conducted measurements of the length of shelf space used for fruits, vegetables, and snack foods items in 419 stores(More)
Collection of sensitive data with the use of video-enhanced, computer-assisted, self-administered interviews (V-CASI) has the potential to reduce interview bias and improve the validity of the study. The purpose of this study was to compare responses to sensitive questions elicited by V-CASI and by face-to-face interview (FTFI) methods. Women attending a(More)
OBJECTIVE Interventions to reduce high-risk behaviors such as sex and substance use among youths have focused mainly on promoting abstinence, refusal skills, and negotiation skills, yet the frequency of high-risk behaviors among youths may also be influenced by opportunity, particularly the amount of time during which they are not supervised by adults. In(More)
Food access among low-income populations has long been a concern in the United States. Recent research on the geographic dimensions of access has focused on economically deprived areas with little retail food activity, referred to as 'food deserts.' We illustrate concepts of urban food access in this descriptive case study from post-Katrina New Orleans. We(More)
Intrauterine growth retardation and preterm birth are more frequent in African-American women and women of lower socio-economic status, but the reasons for these disparities are not fully understood. The physical and social environments in which these women live may contribute to these disparities. We conducted a multilevel study to explore whether(More)
