Findings are drawn from a wider research study nested within this health-based scientific research capacity strengthening initiative that was aimed at gaining an in-depth understanding of the barriers and enablers of gender equitable scientific career progression for researchers in Sub-Saharan Africa.  Methods: We adopted an exploratory qualitative cross-sectional study design. The main method of data collection was in-depth interviews (IDIs) with trainees/research fellows at various career stages affiliated to three purposively selected DELTAS Africa Research Consortia. In addition, key informant interviews (KIIs) with consortia research leaders/directors, co-investigators, and management team were also conducted to corroborate information gathered from the IDIs, and to provide additional insights on the enabling factors/actions and policy processes that were currently in place or proposed to enhance gender equitable career progression. In total, fifty-eight IDIs (32 female and 26 male) and twenty KIIs (4 female and 16 male) were conducted. Interviews were carried out between May and December 2018 in English. Data were analysed inductively based on emergent themes, and aligned to the developed integrated conceptual framework. Results: Three overarching themes were identified. First: micro level efforts - individual coping mechanisms and familial level support. Second: Meso level efforts -existing enabling mechanisms at the institutional level. Third: proposed solutions for positive change towards enhancing gender equitable career progression at micro, meso and macro levels.  Conclusions: These findings have implications for future research capacity strengthening programming, including DELTAS Africa II initiative (2021-2025); they provide valuable insights on potential strategies and actions aiming to narrow gender inequities in scientific career progression in the context of sub-Saharan African research institutions.","PeriodicalId":34179,"journal":{"name":"AAS Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47234174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risky sexual behaviour with poor access to SRH information and interventions increases their vulnerability to adverse SRH outcomes. This study explored the use of modern contraceptives and sexual practices among male and female SIYP (10-24 years) in Nigeria. <b>Methods:</b> This qualitative study used an exploratory research design to guide the development of the focus group discussion (FGD) and in-depth interview (IDI) guides. Participants were asked questions on background information, lived experiences and SRH practices. The FGDs were stratified by sex and age.

Rising prevalence rates of childhood overweight/obesity in Nigeria have been reported, whilst undernutrition continues to be prevalent. This study aimed to estimate the prevalence and distribution of underweight, stunting, thinness, overweight/obesity, and DBM among school-aged children and adolescents in two Nigerian States. <b>Methods:</b> This was a community-based cross-sectional study carried out in Osun and Gombe States. A total of 1,200 children aged 6 - 19 years were recruited using multi-stage sampling technique. Weight, height and data on demographic, socio-economic, household/family characteristics of the children were collected using structured interviewer administered questionnaires. Nutritional status was calculated using the WHO 2007 reference values using BMI-for-age (thinness, overweight/obesity), height-for-age (stunting) and weight-for-age (underweight).

Similarly, while there is increasing prevalence of intimate partner violence (IPV) in Nigeria, its effects on contraceptive use remain unclear. This study examined the influence of IPV on MC use, while adjusting for individual- and community-level confounders. Methods: The study utilized 2018 Nigeria Demographic and Health Survey data. We performed multilevel binary logistic regression analysis on 24,973 married women aged 15-49, who were sexually active and were not pregnant at the time of the survey. Results: Findings show that use of MC was higher among married women who reported experience of IPV than those without IPV exposure. After adjusting for individual-level and contextual factors, the odds of using MC was significantly higher among women who experienced any form of IPV (OR: 1.61, 95% CI: 1.17-2.21, p<0.005) compared to those who reported no IPV experience. Around one-quarter of the total variance in contraceptive use with respect to the different types of IPV could be explained at the community level. Conclusion: The study provides empirical evidence that there is significant community effect on IPV exposure and women’s contraceptive uptake. Attention must therefore be given to the context-specific social and gender norms that affect women’s sexual and reproductive health in Nigeria.","PeriodicalId":34179,"journal":{"name":"AAS Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47969442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The association between young mother’s social independence and NCD status is of policy interest due to its effect on economic and social development. This study aimed to determine the causal relationship between social independence and NCD outcomes among young, single mothers in South Africa. Methods: Data from the South African National Income Dynamics Survey (NIDS) in 2008 and 2017 was used to determine if single mothers developed hypertension, diabetes or asthma by various indicators of social independence, including highest level of education and employment status. The sample was initially made-up of unmarried females (15-24 years old) without any children in 2008. Both fertility and social independence was followed-up to 2017. Results: In total, 66 young females developed an NCD by 2017 and 87% (n=57) of these women had a child in the interim period. Employment of young females increased from 4.78% in 2008 to 37.79% in 2017, but completion of secondary or tertiary education declined from 67.94% in 2008 to 56.01% in 2017. In addition, half (50.88%) of the young females were partially independent by 2017, with only 11.03% being fully independent at this time. Finally, logistic regression results showed that the likelihood of developing an NCD increased if young females with children were not socially independent.

Recent studies have observed vectors resting predominantly outdoors in settings where anti-vector tools are extensively deployed. This present study examined if the outdoor resting behaviour in the vector population, is random or indicative of a consistent preference of one resting site over the other. MethodsMark-release-recapture (MRR) experiments were conducted with outdoor-resting Anopheles gambiae and An. funestus mosquitoes collected from pit shelters, animal houses and granaries in two villages in Northern Ghana. Mosquitoes were marked with fluorescent dyes and released indoors. The experiments were controlled with indoor-resting mosquitoes, which were marked and released outdoors. Species of all recaptured mosquitoes were identified and assessed for consistency in their resting behaviour. ResultsA total of 4,460 outdoor-resting mosquitoes comprising An. gambiae sensu lato (s.l.) (59%) and An. funestus complex (41%) were marked and released. Overall, 31 (0.7%) mosquitoes (25 An. gambiae s.l. and 6 An. funestus complex) were recaptured mostly from outdoor location. Only 3 of the recaptured mosquitoes were found resting indoors where they were released. The majority of the outdoor-recaptured mosquitoes were An. arabiensis (11, 39%), followed by An. coluzzii (7, 25%); whereas the indoor-recaptured mosquitoes were mainly (3) An. coluzzii. For the control experiment, 324 indoor-resting mosquitoes constituting 313 An. gambiae s.l. and 11 An. funestus complex were marked and released. However, none of these was recaptured neither indoors nor outdoors.ConclusionsThe mosquitoes demonstrated the tendency to retain their outdoor-resting behaviour.
