RESUMO
PURPOSE: To identify the influence of gender stereotypes on eating habits among Costa Rican adolescents. DESIGN: Qualitative, descriptive research was used in this study. SETTING: Adolescents and parents were recruited from socioeconomically diverse populations in rural and urban areas of San José, Costa Rica. SUBJECTS: Subjects were 92 adolescents (14 to 17 years old) and 48 parents. METHODS: Focus group data were transcribed and entered into the qualitative data analysis software Atlas.ti version 5.0. Analyses were grounded on the social cognitive theory. RESULTS: Five themes emerged from the focus group discussions: (1) Costa Rican adolescents associate the consumption of moderate quantities of healthy foods with femininity and male homosexuality. (2) The consumption of hearty portions of nonhealthy foods was associated with masculinity and male heterosexuality. (3) There is an emerging view that it is acceptable for heterosexual male adolescents to take care of their bodies through healthy eating. (4) Body care among female adolescents is an element of femininity and body image. (5) Parents reinforce their daughters' persistent concern with weight control because they perceive it as feminine behavior. CONCLUSION: Health promoters should be aware of the existing and changing food stereotypes around gender as an avenue for the promotion of healthy eating.

PURPOSE: To test the effects of a physical-cognitive exercise intervention on gait parameters under dual-task conditions in community-dwelling older adults. DESIGN: A repeated-measures quasi-experimental design, with control and exercise groups, was used. SETTING: Study participants consist of a convenience sample recruited from senior citizens' centers in Monterrey, Mexico. SUBJECTS: A total of 143 sedentary participants ages 65 to 92 years per group participated. INTERVENTION: A combined 45- to 60-minute program of physical and cognitive exercises was conducted in three weekly sessions during 12 weeks for the exercise group. Measures . The spatial gait parameters of speed (cm/s), step width, and stride length (cm); and the temporal parameters of single and double support time, cadence (steps per minute), and swing time(s) were measured using the GaitRite. Counting backwards or naming animals represented cognitive performance. ANALYSIS: Two (groups: exercise group vs. control group) by three (time: baseline, week 6, and week 12) repeated-measures multivariate analysis of variance (MANOVA) was applied. RESULTS: Repeated-measures multivariate analysis of variance revealed a significant group effect (Wilks lambda F4,279 = 6.78, p < .001); univariate analysis showed significant differences for gait speed (m/s), stride length, cadence, step width, and double support time. Time-by-group interaction showed significance in gait speed and stride length. CONCLUSION: The exercise group participants showed increased gait speed, cadence, and stride length, and reduced their step width and time spent with both feet on the ground. Walking while simultaneously performing a cognitive task might prepare older adults for competing/interfering demands from their environments. The protective health benefits of this intervention remain to be investigated.
