Comparisons were made between traditional and innovative methods to determine which was more effective in increasing breastfeeding duration. Over a 32 month period, 197 prenatal women were assigned to either a control (C, n = 139) or an experimental (E, n = 51) group. The C group received standard breastfeeding education, while the E group received standard education in addition to information about infant hunger cues. Cox Regression and Kap-lan- Meier analysis were performed. Estimated mean number of weeks for C and E groups to continue breastfeeding was 14.3 + 17.4 weeks and 18.5 + 17.1 weeks, respectively. At 26 weeks, duration of breastfeeding approached significance (chi square = 2.907, df = 1, p = 0.088), indicating probability of continuing to breastfeed was about 28% better for those in E group when compared to C group. Duration of breastfeeding may increase when prenatal women are taught to identify infant behavior such as hunger cues.展开更多

The 28 day study was divided into two experimental periods of 14 days each. For the first 14 days, Group 1 (n = 6) received LC diet (30 grams carbohydrate/day with ad libitum intake of protein and fat), and group 2 (n = 8) received MC diet (60 grams carbohydrate/day with ad libitum intake of protein and fat). After 14 days, there was a crossover of the diets. Two random 24-hour diet records, urinary ketones, and daily emotional and physical well-being journals evaluated participants’ dietary compliance. Height, weight, body mass index, and urine ketones were assessed at baseline, days 14 and 28. A 2 × 2 ANOVA was conducted to examine the difference between groups and to determine if a difference existed from baseline to the end of the diet period. During the study period, ir- respective of carbohydrate levels, a vast majority of participants had above or below the recommended intake of carbo- hydrates, indicating non-compliance due to various reasons. During each experimental period, although weight loss differences between groups over time did not exist, there was a significant weight loss within subjects over time (p < 0.01). Presence of urinary ketones during the dietary interventions were not statistically significant. In conclusion, mod-ified carbohydrate diets were effective with weight loss;however participants were non-compliant with their de- fined dietary protocols.展开更多

Female employees at a Mid-Western university were invited to participate in an on-line survey. The 26-itemized Wo- men’s Health Survey (WHS) included questions regarding demographics, menopausal stage, experience of hot flashes, consumption of caffeinated beverages and alcohol, and participation in PA. One-hundred and ninety-six women completed the study. Ordinary Least Squares regressions revealed PA, caffeine, and alcohol intake were significant in predicting the severity of hot flashes (R2 = 0.068, F(6,180) = 2.195, p = 0.046), though they did not predict frequency of hot flashes (R2 = 0.043, F(6,184) = 1.39, p = 0.221). Participation in aerobic PA increased frequency of hot flashes (p = 0.031);while higher intensity of aerobic PA had an inverse relationship on both frequency and severity of hot flashes (p = 0.011, p = 0.003, respectively). Spearman correlations demonstrated a positive relationship between caffeinated soda intake and frequency (r = 0.17, p = 0.06) and severity (r = 0.19, p = 0.04) of hot flashes. Beverage consumption and PA may predict severity of hot flashes in women. Less frequent, higher intensity aerobic PA may lead to fewer, less severe hot flashes.展开更多
