Life stage influences on U.S. South Asian women's physical activity.

PURPOSE: South Asian (SA) women in the United States report extremely low rates of leisure time physical activity (PA) compared with women in other ethnic minority groups. This study explored SA women's perspectives on PA during different life stages. DESIGN: This is a community-based participatory research study that used focus groups. SETTING: The study setting was a community-based organization that provides social services to SA immigrants in Chicago, Illinois. PARTICIPANTS: The study team conducted six focus groups (in English and Hindi) with 42 SA women, ages 18 to 71 years. METHOD: A semistructured interview guide was used to foster discussion about perceptions of, barriers to/facilitators of, and suggestions for PA programs. Discussions were transcribed and independently coded by two reviewers using thematic content analysis and guided by a coding scheme that was developed a priori. RESULTS: Participants said that different life stages strongly influenced their PA. PA decreased after marriage and having children. Chronic diseases constrained older women from more vigorous PA. Barriers to PA among younger women were family disapproval and perceptions that PA is unnecessary if you are "skinny." Women agreed that PA is not a priority within the culture, and that interventions must take into account cultural, religious, and family context. CONCLUSION: Sociocultural norms, family constraints, and lack of awareness about the benefits of PA strongly influenced PA among SA women. Culturally salient intervention strategies might include programs in trusted community settings where women can exercise in women-only classes with their children, and targeted education campaigns to increase awareness about the benefits of PA across life stages.

The effects of beverages on plaque acidogenicity after a sugary challenge.

BACKGROUND: Caries prevention traditionally has emphasized the restriction of cariogenic foods and beverages, but it has placed less emphasis on how the choice, combination and sequence of consumed foods and beverages may help reduce plaque acidogenicity. The authors conducted a study to examine whether whole milk, 100 percent apple juice or tap water affect dental plaque acidity in people after a sugary challenge. METHODS: Twenty adults participated in a randomized controlled crossover study. Participants consumed four combinations of foods: 20 grams of dry sugary Froot Loops (FL) (Kellogg's, Battle Creek, Mich.) cereal, 20 g of FL followed by 50 milliliters of milk (FL/milk), 20 g of FL followed by 50 mL of juice (FL/juice) and 20 g of FL followed by 50 mL of water (FL/water). The authors used a touch microelectrode to take plaque pH readings at the interproximal space just below the contact area between the maxillary premolars on both left and right sides at two and five minutes after FL consumption and at two to 30 minutes after milk, juice or water consumption. RESULTS: Consumption of FL plaque pH (standard deviation [SD]) was 5.83 (0.68) at 30 minutes, whereas plaque pH (SD) in the FL/milk group was 6.48 (0.30), which was significantly higher than that for FL/juice (5.83 [0.49]) or FL/water (6.02 [0.41]) (P < .005) at 35 minutes. CONCLUSION: Drinking milk after a sugary cereal challenge significantly reduced plaque pH drop due to the sugary challenge. PRACTICAL IMPLICATIONS: When discussing the cariogenicity of foods and beverages with patients, dentists and other health care professionals should emphasize that the order of ingesting sugary and nonsugary foods is important and may affect their oral health.
