Sexting using internet-enabled mobile phones is increasingly becoming central to college students’ communication. Understanding prevalence rates and psychological predictors in an understudied population in sub-Saharan Africa therefore warrants concern. This survey study sought to examine (a) sexting prevalence rates; (b) impulsivity traits and sexting; and (c) whether emotions moderate the relationship between impulsivity traits and sexting among college students. Data from undergraduate students (N = 464; M(SD) age = 22.84 (.91); 50.4% female) were collected using a questionnaire measuring impulsivity, emotions and engagement in sexting and analysed using descriptive statistics, t-tests and regression analysis. Moderation analysis was conducted using the PROCESS macro for SPSS. Results show that sexting was reported by over half the sample and men were significantly more likely to send and respond to sexts. Lack of premeditation predicted sending but not responding; positive urgency predicted responding but not sending; and sensation seeking predicted both aspects of sexting. Desire, fear and happiness moderated the relationship between impulsivity traits and sexting. Findings suggest that under specific heightened emotions, individuals with impulsivity traits are more likely to engage in sexting.

Background Diabetes mellitus is a growing worldwide health challenge especially in sub-Saharan Africa. While the use and effectiveness of diabetes self-management interventions is well documented in high-income countries, little information exists in sub-Saharan Africa. Therefore, this study attempted to synthesize information in the literature on the use and efficacy of peer support and social networking in diabetes self-management in Kenya and Uganda. Objective The purpose of this scoping review is to summarize research on the extent of use and efficacy of peer support and social networking interventions in diabetes self-management in Kenya and Uganda. Design We searched PubMed, ScienceDirect and Cochrane Library databases for articles reporting peer support and social networking interventions in Kenya and Uganda published in English between 2000 and September 2021. Key words encapsulated three major themes: peer support, social networking and self-management. Hand searches were also conducted to select eligible papers. Data was extracted using a form prepared and piloted in line with PRISMA-ScR guidelines. Results Thirteen peer reviewed articles were selected for analysis. Eleven studies reported peer support interventions while two focused on social networks in diabetes self-management. Peer support and social networking interventions incorporated microfinance and group medical visits, diabetes self-management education, telephone support and Medication Adherence Clubs. Most interventions were delivered by multidisciplinary teams comprising nurses and other professionals, peer educators, peer leaders and community health workers. Most interventions were effective and led to improvements in HbA1c and blood pressure, eating behaviors and physical activity and social support. Conclusions The limited studies available show that peer support and social networking interventions have mixed results on health and other outcomes. Importantly, most studies reported significant improvements in clinical outcomes. Further research is needed on the nature and mechanisms through which peer support and social network characteristics affect health outcomes.
