Social Media Engagement

Background. African American women (AAW) are in a unique position to be recruited into mobile (mHealth) weight management research and programs due to their high rates of obesity and their high ownership of smartphones. Aim. This study examined smartphone usage, social media engagement, and willingness to participate in mHealth weight management among AAW in north-central Florida, United States. Methods. A self-administered survey was completed by a convenience sample of 425 smartphone owners in north-central Florida. Results. Mean age was 34.84 ± 13.74, with age distribution of 18 to 29 (45%), 30 to 50 (39%), and 51+ years (17%). Mean body mass index was 29.52 ± 8.18. Most used smartphones to access the Internet daily and were engaged with eight social media sites, such as Facebook (85%), YouTube (75%), and Google+ (57%). Compared to those 51+, those 18 to 29 were more likely to use YouTube (odds ratio [OR] = 2.52, p = .017) and Instagram (OR = 10.90, p < .0001), but they were less likely to use Google+ (OR = 0.40, p = .009). Compared to those 51+, those 30 to 50 were more likely to use Instagram (β = 1.28, OR = 3.61, p = .014) and Facebook (β = 1.04, OR = 2.84, p < .006). Most were willing to participate in research that used text messages (73%), smartwatches/fitness trackers (69%), and smartphone apps (68%). Compared to those 51+, women 18 to 29 were more likely to report willingness to use a smartphone app (OR = 5.45, p < .0001) as were those 30 to 50 (OR = 3.14, p < .0001). Conclusion. AAW’s high ownership of smartphones, use of mHealth apps and tools, and willingness to participate in mHealth research has the potential to curb the obesity epidemic by participating in mHealth weight management programs and research.

The Difference

Abstract. An association between intelligence at age 7 and a set of five single-nucleotide polymorphisms (SNPs) has been identified and replicated. We used this composite SNP set to investigate whether the associations differ between boys and girls for general cognitive ability at ages 2, 3, 4, 7, 9, and 10 years. In a longitudinal community sample of British twins aged 2-10 (n > 4,000 individuals), we found that the SNP set is more strongly associated with intelligence in males than in females at ages 7, 9, and 10 and the difference is significant at 10. If this finding replicates in other studies, these results will constitute the first evidence of the same autosomal genes acting differently on intelligence in the two sexes.

Hierarchical Regression

Despite a consistent body of work documenting associations between racial discrimination and negative mental health outcomes, the utility and validity of these findings have recently been questioned because some authors have posited that personality traits may account for these associations. To test this hypothesis in a community sample of African Americans ( n = 419, age: M = 43.96 years), we used bivariate relations and hierarchical regression analyses to determine whether racial discrimination accounted for additional variance in depression, anxiety, and posttraumatic stress symptoms beyond the role of personality. Bivariate relations between personality traits and racial discrimination were small and positive (i.e., rs ≈ .10). Regression results demonstrated that racial discrimination accounted for variance in depression, anxiety, and posttraumatic stress independent of personality traits ( ps < .01). These results suggest that personality traits do not fully explain associations between racial discrimination and negative mental health outcomes, further supporting the detrimental impact of racial discrimination on the mental health of African Americans.

Purpose The purpose of this study is to examine the association of individual, community, and health system factors on quality of life among inner-city African Americans with type 2 diabetes. Methods Primary data from a cross-sectional study with a community sample of 241 inner-city African Americans with type 2 diabetes were analyzed. Paper-based surveys were administered in which the SF-12 was used to capture the physical component (PCS) and mental component (MCS) of quality of life. Four regression approaches (sequential, stepwise with backward and forward selection, and all possible subsets regression) were used to examine the influence of individual, community, and health system factors on PCS and MCS after adjusting for relevant covariates using a conceptual framework. Results In fully adjusted models, having less than a high school education and having major depression were associated with lower quality-of-life scores for MCS across all 4 regression approaches. Being employed was positively associated with better quality-of-life scores for PCS across all 4 regression approaches. PCS was higher across all 4 regression approaches for those reporting a history of trauma. At the health systems level, usual source of care was associated with better PCS across 3 regression approaches. Conclusions These results highlight key factors that influence quality of life among inner-city African Americans with type 2 diabetes that could be targets for interventions in this population. However, additional research is needed to understand existing pathways that may be driving many of these relationships.

Spiders and their webs are predictable sources of insect cadavers. A small number of animals regularly exploit this resource, either as kleptoparasites or commensals, depending on whether symbionts compete for the same prey (see Robinson and Robinson, 1977, for more detailed terminology). Among the thieves are specialized spiders (citations in Vollrath 1979a, 1979b), mature male and juvenile spiders (Stowe 1978, citations in Nyffeler and Benz 1980), Hemiptera (Davis and Russell 1969), a hummingbird (takes webbing in addition to small insects, Young 1971), panorpid scorpion-flies (Thornhill 1975), Lepidoptera larvae (Robinson 1978), wasps (Jeanne 1972), damselflies (Vollrath 1977), and a handful of flies (reviews in Knab 1915; Bristowe 1931, 1941; Lindner 1937; Richards 1953; Robinson and Robinson 1977). Only a few of the reports on Diptera kleptoparasites originate from North America (McCook 1889, Frost 1913, Downes and Smith 1969). With a single exception (Downes and Smith 1969), all of the previously described kleptoparasitic flies belong to the Brachycera and Cyclorrhapha. We report here on a surprisingly diverse kleptoparasitic Diptera fauna in north central Florida with a cecidomyiid (Nematocera) as its dominant member.
