Ecological Momentary Assessment of the Breakfast, Lunch, and Dinner Family Meal Environment in Racially/Ethnically Diverse and Immigrant Households.

OBJECTIVE: To describe meal characteristics across breakfast, lunch, and dinner family meals in racially/ethnically diverse and immigrant/refugee households via ecological momentary assessment; identify real-time meal characteristics associated with family meal frequency; and identify qualitative themes regarding parents' perspectives about meal characteristics and meal types that influence family meal frequency. DESIGN: Cross-sectional study. SETTING: In-home visits. PARTICIPANTS: Children aged 5-7 years (n = 150) and their families from diverse and low-income households. MAIN OUTCOME MEASURE(S): Mixed methods. ANALYSIS: Multiple linear regression and hybrid deductive and inductive content analysis. RESULTS: Quantitative results indicated several similar meal characteristics occurring across weekdays and weekend days and by meal type (eg, parent prepared the meal, food mostly homemade, meal eaten at table) and some significant negative associations (P < .05) between meal characteristics and family meal frequency (eg, fast food for family meals). Eight main qualitative themes with several subthemes supported and expanded the quantitative findings and added depth to interpretation of the findings. CONCLUSIONS AND IMPLICATIONS: Results identified specific meal characteristics both quantitatively and qualitatively that may inform the development of interventions to increase the frequency of family meals so that more families can benefit from the protective nature of family meals.

Family meals then and now: A qualitative investigation of intergenerational transmission of family meal practices in a racially/ethnically diverse and immigrant population.

Having frequent family meals has consistently been associated with better health outcomes in children/adolescents. It is important to identify how intergenerational transmission of family meal practices occurs to help families benefit from the protective nature of family meals. Limited studies exist that explore the intergenerational transmission of family meal practices, particularly among racially/ethnically diverse and immigrant populations. This study explores how parents describe differences and similarities between meals "then" and "now", lessons they learned as children about family meals, lessons they passed onto their children, the challenges of carrying out family meals, and how families handle the barriers/challenges to intergenerational transmission of family meal practices. The study was conducted with a sample of African American, Native American, Latino, Hmong, Somali, and White families (25/category). Qualitative themes were explored with the overall sample, by race/ethnicity, immigrant status, and by time in the United States (US) as an immigrant. Parents overwhelmingly reported learning as children that family meals were important and conveying this message to their own children. Differences existed among racial/ethnic groups and time in the US as an immigrant. For example, Somali parents frequently endorsed having no challenges with intergenerational transmission of family meal practices. Immigrant parents in the US for a longer period of time were more likely to endorse learning/teaching about family meal importance, that the food eaten now is different than growing up, that a chaotic environment is a challenge to having family meals, and that they accommodate family member's schedules when planning family meals. Results demonstrate that exploring a parent's early family meal experiences may be important when intervening with parents from diverse racial/ethnic and immigrant populations when trying to improve or increase family meal practices.

Host immunity, nutrition and coinfection alter longitudinal infection patterns of schistosomes in a free ranging African buffalo population.

Schistosomes are trematode parasites of global importance, causing infections in millions of people, livestock, and wildlife. Most studies on schistosomiasis, involve human subjects; as such, there is a paucity of longitudinal studies investigating parasite dynamics in the absence of intervention. As a consequence, despite decades of research on schistosomiasis, our understanding of its ecology in natural host populations is centered around how environmental exposure and acquired immunity influence acquisition of parasites, while very little is known about the influence of host physiology, coinfection and clearance in the absence of drug treatment. We used a 4-year study in free-ranging African buffalo to investigate natural schistosome dynamics. We asked (i) what are the spatial and temporal patterns of schistosome infections; (ii) how do parasite burdens vary over time within individual hosts; and (iii) what host factors (immunological, physiological, co-infection) and environmental factors (season, location) explain patterns of schistosome acquisition and loss in buffalo? Schistosome infections were common among buffalo. Microgeographic structure explained some variation in parasite burdens among hosts, indicating transmission hotspots. Overall, parasite burdens ratcheted up over time; however, gains in schistosome abundance in the dry season were partially offset by losses in the wet season, with some hosts demonstrating complete clearance of infection. Variation among buffalo in schistosome loss was associated with immunologic and nutritional factors, as well as co-infection by the gastrointestinal helminth Cooperia fuelleborni. Our results demonstrate that schistosome infections are surprisingly dynamic in a free-living mammalian host population, and point to a role for host factors in driving variation in parasite clearance, but not parasite acquisition which is driven by seasonal changes and spatial habitat utilization. Our study illustrates the power of longitudinal studies for discovering mechanisms underlying parasite dynamics in individual animals and populations.
