Background: Lack of breastfeeding support is a common barrier reported by African American mothers, whose breastfeeding rates remain significantly below the national average. Despite mothers’ reported use of social network sites to access support on topics relating to child rearing, few studies have examined their use to exchange breastfeeding support. Research aims: To describe (1) the experiences of African American mothers who participate in breastfeeding support groups on Facebook and (2) the breastfeeding beliefs, practices, and outcomes for this population of mothers. Methods: This was a prospective, cross-sectional qualitative study with an online focus group design. The study was guided by Black Feminist Thought and an integrated model of behavior prediction. Four online focus groups ( N = 22) were conducted using video conferencing during September 2017 with African American mothers who were participating in breastfeeding support groups on Facebook. Results: Thematic analysis was used to develop four themes and two subthemes, including creating a community for Black mothers, online interactions and levels of engagement, advantages of participating in online support groups, critiques of online support groups, empowerment of self and others, and shifts in breastfeeding perceptions and decisions. Among participants in this study, positive imagery of African American breastfeeding mothers and ongoing support from women with shared experiences improved confidence with public breastfeeding and prolonged goals for breastfeeding duration. Conclusion: Receiving peer support within Facebook communities may positively influence breastfeeding norms and confidence in breastfeeding, help mothers to overcome breastfeeding challenges, and ultimately extend intended breastfeeding duration.

The increasing numbers of lifestyle related chronic diseases in developing countries call for awareness, early detection, and effective management. The objective of this paper is to report the prevalence of undiagnosed hypertension, diabetes, overweight/obesity, and anemia among residents of selected communities in Ghana. The data comes from a community screening conducted in Ghana as part of the University of Georgia Summer Service Learning Program. Descriptive statistics were used to summarize the data while chi-square and independentt-test compared groups. A total of 976 participants (37.9% males and 62.1% females), 18 years and older, were screened. Mean age was46.25±17.14years, BMI was25.44±5.26 kgm−2, and hemoglobin was12.04±2.22 g/dL. 3.1% and 12.6% reported existing diagnosis for diabetes and hypertension, respectively. Almost half (47.8%) were overweight/obese; 27.0% were hypertensive while 34.0% had diabetes. Also, 28.8% males compared to 37.8% females had diabetes (P=0.015), while 28.2% males compared to 26.2% females were hypertensive (P=0.635). There were differences in BMI (P<0.0001), anemia (P=0.007), and undiagnosed diabetes (P<0.0001) and hypertension (P<0.0001) by community (Takoradi versus Cape Coast) where the screening took place. Findings from the screening exercise call for improved public health education with a focus on lifestyle habits and health seeking behaviors among Ghanaians.

Malnutrition is a major concern in low- and middle-income countries (LMIC), but the full extent of nutritional deficiencies remains unknown largely due to lack of accurate assessment methods. This study seeks to develop and validate an objective, passive method of estimating food and nutrient intake in households in Ghana and Uganda. Household members (including under-5s and adolescents) are assigned a wearable camera device to capture images of their food intake during waking hours. Using custom software, images captured are then used to estimate an individual's food and nutrient (i.e., protein, fat, carbohydrate, energy, and micronutrients) intake. Passive food image capture and assessment provides an objective measure of food and nutrient intake in real time, minimizing some of the limitations associated with self-reported dietary intake methods. Its use in LMIC could potentially increase the understanding of a population's nutritional status, and the contribution of household food intake to the malnutrition burden. This project is registered at clinicaltrials.gov (NCT03723460).

Knowing the amounts of energy and nutrients in an individual’s diet is important for maintaining health and preventing chronic diseases. As electronic and AI technologies advance rapidly, dietary assessment can now be performed using food images obtained from a smartphone or a wearable device. One of the challenges in this approach is to computationally measure the volume of food in a bowl from an image. This problem has not been studied systematically despite the bowl being the most utilized food container in many parts of the world, especially in Asia and Africa. In this paper, we present a new method to measure the size and shape of a bowl by adhering a paper ruler centrally across the bottom and sides of the bowl and then taking an image. When observed from the image, the distortions in the width of the paper ruler and the spacings between ruler markers completely encode the size and shape of the bowl. A computational algorithm is developed to reconstruct the three-dimensional bowl interior using the observed distortions. Our experiments using nine bowls, colored liquids, and amorphous foods demonstrate high accuracy of our method for food volume estimation involving round bowls as containers. A total of 228 images of amorphous foods were also used in a comparative experiment between our algorithm and an independent human estimator. The results showed that our algorithm overperformed the human estimator who utilized different types of reference information and two estimation methods, including direct volume estimation and indirect estimation through the fullness of the bowl.

The purpose of this formative, cross-sectional study was to describe independent eating occasions (iEOs) among a convenience sample of low-income early adolescents (10–13 years, n = 46) in 10 U.S. states, including environmental context, foods selected and reasons for selection, and parental rules about foods consumed. Participants took pictures of all foods consumed over 24 h and participated in semi-structured interviews to describe the context of each eating occasion using the pictures as a guide. Responses based on a total of 304 eating occasions were coded to classify foods based on United States Department of Agriculture (USDA) MyPlate food groups and to characterize parental rules and reasons for food selection. Average age was 10.9 ± 1.1 years and 60% were female. Approximately 58% of eating occasions were classified as iEOs with approximately 65% as snacks. Most iEOs took place at home. Foods frequently consumed during iEOs were from the sweets, total fruit, dairy, and whole fruit food categories. Primary parental rules for iEOs focused on avoiding certain foods and not eating too much. Early adolescents selected foods for convenience, taste preferences, and availability. Foods selected during iEOs were based on parent, household and early adolescent factors, which could be addressed to influence overall diet quality.

Parents play an important role in developing the eating behaviors of their children by adopting specific parenting practices. As the prevalence of obesity is high amongst African American adolescents, investigations into associations of specific parenting practices and adolescents’ eating behaviors are essential. In this exploratory study, 14 African American parent–adolescent dyads were interviewed to characterize the influence of eight different parenting practices on the consumption of three main food categories (dairy, fruits and vegetables, and unhealthy snacks). The results revealed that authoritarian parenting practices were correlated with a higher BMI percentile in adolescents, whereas modeling and monitoring are correlated with a higher parent BMI. In addition, reasoning, monitoring, modeling, and authoritative parenting practices were associated with less unhealthy snack consumption among adolescents. Reasoning and monitoring were the only parenting practices associated with higher fruit and vegetable consumption. Finally, a significant correlation was found between eating fruits and vegetables and unhealthy snacks and the location of eating. In conclusion, different parenting practices and environmental factors may impact BMI and food consumption of African American dyads. The results of this study can be used to guide improvement in, and/or development of, nutritional education interventions considering the cultural differences of racial minorities.
