Item Relationship between Live-In Grandparents and Grandchild’s Health and Well-Being in Palestinian Refugees in Lebanon(MDPI, 2022-12-26) Sheikomar, Olfat B.; Ghattas, Hala; Sahyoun, Nadine R.Grandparents (GP) play influential roles in grandchildren’s health, behavior, and life. However, this relationship has not been examined in the Arab region. This study assesses whether the presence of GP in the household is associated with grandchildren’s health and wellbeing. Health status was determined by a child experiencing chronic health conditions or an acute illness, and wellbeing was determined based on school attendance and child labor. Data were collected through surveys conducted in 2010 and 2015 of representative samples of Palestinian refugees living in Lebanon. Multivariate logistic regression showed that, even after controlling for potential confounders, including the presence of parents in the household and household food insecurity (FI), the presence of live-in GP was associated with lower odds of children experiencing acute illnesses (OR 0.74 95% CI 0.62–0.92) and higher odds of attending school (OR 2.22 95% CI 1.28–5.33), but not child labor. The presence of GP in the household may be protective to grandchildren’s health status and school attendance in this population.Item Electronic Interventions to Improve Health Behaviors in College Students(2014) Schweitzer, Amy; Lei, David K.Y.; Nutrition; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Introduction: In transitioning from adolescence to adulthood, college students are faced with significant challenges to their health habits. Time, independence and stress have been known to result in poor eating and exercise habits which can lead to increased disease risk. Objective: To assess whether an electronic health intervention can improve health habits in college students. Methods: A 24-week diet and physical activity program was delivered by e-mail to 148 college students. The intervention involved weekly tailored, interactive diet and physical activity goals. The control group received non-diet-non-exercise-related health fact sheets. Baseline, 12-week, and 24-week diet and physical activity surveys were completed online. BMI, neck circumference, waist circumference, and percent fat mass (FM%) by bioelectrical impedance analysis were measured at baseline, week 12 and week 24. Results: Students were 18-20 years old 70% female from a diverse college campus (46% Caucasian, 23% Asian, 20% African American, 5% Hispanic, and 6% other). At baseline, 23% were overweight/obese by BMI, 88% reported consuming <5 fruits and vegetables daily, 59% consumed >10% of kcalories from saturated fat, although 91% met or exceeded 150 minutes/week of moderate-vigorous exercise. Seventy-one percent of students completed all study visits. Repeated measures ANOVA showed a significant treatment by linear time interaction for saturated fat. A significant change from baseline saturated fat intake was detected between the treatment groups at week 24 (mean change ± standard error 0.7±0.42% of kcal for control and -0.3±0.30% of kcal for intervention). Differences in saturated fat intake between the two treatment groups were more evident in those whose intake exceeded recommendations. BMI, neck circumference, waist circumference, FM%, weekly minutes of moderate and vigorous physical activity as well as intake of fruit, vegetables, and added sugar were not significantly different between treatment groups. Conclusion: College students enrolled in an interactive electronic health intervention decreased saturated fat intake compared to control. Furthermore, the decrease observed in the intervention group was mainly due to those whose intake of saturated fat intake was above the recommended 10% of total kcalories. Further development of the electronic intervention program is needed to maximize health benefits in college students.Item Dietary Patterns, Metabolic Risk and Survival in Older Adults(2008-10-28) Anderson, Amy Louise; Sahyoun, Nadine R.; Nutrition; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Background: Recent evidence suggests that older adults' diets can appreciably impact their health. Dietary patterns may better capture the multifaceted effects of diet on health than individual nutrients or foods. Objectives: The purpose of this study was to identify the dietary patterns of a cohort of older adults, and examine relationships with body composition, insulin sensitivity, systemic inflammation, and survival. The influence of a polymorphism in the peroxisome proliferator-activated receptor-γ (PPAR-γ) gene was considered. Design: The Health, Aging and Body Composition (Health ABC) Study is a prospective cohort study of 3075 older adults. Participants' body composition, genetic variation, glucose metabolism, systemic inflammation, and vital status were evaluated in detail. Food intake was assessed with a modified Block food frequency questionnaire (FFQ), and dietary patterns were derived by cluster analysis. Results: Six clusters were identified, including a 'Healthy foods' cluster characterized by higher intake of lowfat dairy products, fruit, whole grains, poultry, fish and vegetables. An interaction was found between dietary pattern and PPAR-γ Pro12Ala genotype in relation to body composition. While Pro homozygotes in the 'Healthy foods' cluster did not differ significantly in body composition from those in other clusters, men with the Ala allele in the 'Healthy foods' cluster had significantly lower adiposity than those in other clusters. The 'Healthy foods' cluster had lower fasting insulin and HOMA-IR values than the 'High-fat dairy products' and 'Breakfast cereal' clusters, while no differences were found in fasting or 2-hour glucose. With respect to inflammation, the 'Healthy foods' cluster had lower levels of IL-6 than the 'High-fat dairy products' and 'Sweets and desserts' clusters, and did not differ in CRP or TNF-α. The 'Healthy foods' cluster also had a lower risk of mortality than the 'High-fat dairy products' and 'Sweets and desserts' clusters, and more years of healthy life and more optimal nutritional status than the other clusters. Conclusion: A dietary pattern consistent with current guidelines to consume relatively high amounts of vegetables, fruit, whole grains, poultry, fish and lowfat dairy products may reduce the metabolic risk and improve the nutritional status, quality of life and survival of older adults.
