Perceived Risks Associated with Contraceptive Method Use among Men and Women in Ibadan and Kaduna, Nigeria
Research shows that side effects are often the most common reason for contraceptive non-use in Nigeria; however, research to date has not explored the underlying factors that influence risk and benefit perceptions associated with specific contraceptive methods in Nigeria. A qualitative study design using focus group discussions was used to explore social attitudes and beliefs about family planning methods in Ibadan and Kaduna, Nigeria. A total of 26 focus group discussions were held in 2010 with men and women of reproductive age, disaggregated by city, sex, age, marital status, neighborhood socioeconomic status, and—for women only—family planning experience. A discussion guide was used that included specific questions about the perceived risks and benefits associated with the use of six different family planning methods. A thematic content analytic approach guided the analysis. Participants identified a spectrum of risks encompassing perceived threats to health (both real and fictitious) and social concerns, as well as benefits associated with each method. By exploring Nigerian perspectives on the risks and benefits associated with specific family planning methods, programs aiming to increase contraceptive use in Nigeria can be better equipped to highlight recognized benefits, address specific concerns, and work to dispel misperceptions associated with each family planning method
DNA Barcoding Bromeliaceae: Achievements and Pitfalls
<div><h3>Background</h3><p>DNA barcoding has been successfully established in animals as a tool for organismal identification and taxonomic clarification. Slower nucleotide substitution rates in plant genomes have made the selection of a DNA barcode for land plants a much more difficult task. The Plant Working Group of the Consortium for the Barcode of Life (CBOL) recommended the two-marker combination <em>rbcL</em>/<em>matK</em> as a pragmatic solution to a complex trade-off between universality, sequence quality, discrimination, and cost.</p> <h3>Methodology/Principal Findings</h3><p>It is expected that a system based on any one, or a small number of plastid genes will fail within certain taxonomic groups with low amounts of plastid variation, while performing well in others. We tested the effectiveness of the proposed CBOL Plant Working Group barcoding <em>markers</em> for land plants in identifying 46 bromeliad species, a group rich in endemic species from the endangered Brazilian Atlantic Rainforest. Although we obtained high quality sequences with the suggested primers, species discrimination in our data set was only 43.48%. Addition of a third marker, <em>trnH–psbA</em>, did not show significant improvement. This species identification failure in Bromeliaceaecould also be seen in the analysis of the GenBank's <em>matK</em> data set. Bromeliaceae's sequence divergence was almost three times lower than the observed for Asteraceae and Orchidaceae. This low variation rate also resulted in poorly resolved tree topologies. Among the three Bromeliaceae subfamilies sampled, Tillandsioideae was the only one recovered as a monophyletic group with high bootstrap value (98.6%). Species paraphyly was a common feature in our sampling.</p> <h3>Conclusions/Significance</h3><p>Our results show that although DNA barcoding is an important tool for biodiversity assessment, it tends to fail in taxonomy complicated and recently diverged plant groups, such as Bromeliaceae. Additional research might be needed to develop markers capable to discriminate species in these complex botanical groups.</p> </div
Updated international tuberous sclerosis complex diagnostic criteria and surveillance and management recommendations
Background
Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disease affecting multiple body systems with wide variability in presentation. In 2013, Pediatric Neurology published articles outlining updated diagnostic criteria and recommendations for surveillance and management of disease manifestations. Advances in knowledge and approvals of new therapies necessitated a revision of those criteria and recommendations.
Methods
Chairs and working group cochairs from the 2012 International TSC Consensus Group were invited to meet face-to-face over two days at the 2018 World TSC Conference on July 25 and 26 in Dallas, TX, USA. Before the meeting, working group cochairs worked with group members via e-mail and telephone to (1) review TSC literature since the 2013 publication, (2) confirm or amend prior recommendations, and (3) provide new recommendations as required.
Results
Only two changes were made to clinical diagnostic criteria reported in 2013: “multiple cortical tubers and/or radial migration lines” replaced the more general term “cortical dysplasias,” and sclerotic bone lesions were reinstated as a minor criterion. Genetic diagnostic criteria were reaffirmed, including highlighting recent findings that some individuals with TSC are genetically mosaic for variants in TSC1 or TSC2. Changes to surveillance and management criteria largely reflected increased emphasis on early screening for electroencephalographic abnormalities, enhanced surveillance and management of TSC-associated neuropsychiatric disorders, and new medication approvals.
Conclusions
Updated TSC diagnostic criteria and surveillance and management recommendations presented here should provide an improved framework for optimal care of those living with TSC and their families

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021
BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

SEXUAL NORMS, GENDER ROLE BELIEFS, CONDOM ATTITUDES AND SEXUAL BEHAVIORS AMONG YOUTH IN HANOI, SHANGHAI AND TAIPEI
Background
Health behaviors are increasingly being understood through the lens of attitudes and beliefs that contribute to them. Youth in Asia face a world very different from that of their parents, however there is a dearth of research on sexual and reproductive health issues among Asian youth. Understanding the ways in which attitudes and beliefs shape sexual behaviors is an important first step in designing appropriate programming that empowers Asian youth to live healthy lives.
Methods
Using data from unmarried youth surveyed in the Three Cities Study of Hanoi, Shanghai and Taipei, I conducted exploratory, confirmatory and multiple group factor analyses to develop and examine scales for gender role beliefs, sexual norms and condom attitudes. Through these analyses I proposed and confirmed the factor structure of each latent construct, tested the fit of the models, and evaluated the heterogeneity of each scale by city, sex, and city and sex groupings. I used logistic regression analyses to examine the association of sexual norms and gender role beliefs with sexual experience on all unmarried youth. I performed multiple logistic regression modeling to examine the association between condom attitudes and condom use at first and last sex among all sexually experienced, unmarried youth.
Results
Exploratory analyses revealed a four item sexual norms scale, a three item gender role beliefs scale, and a four item condom attitudes scale, each showing acceptable reliability. Confirmatory analyses of both gender role beliefs and sexual norms showed acceptable fit, while sexual norms showed less than acceptable model fit. Multiple group analyses showed gender role beliefs to vary distinctly by city, sex, and city and sex grouping. Multiple group analyses showed that while condom attitudes appear to be invariant across sex, they vary by city and city and sex group.
Sexual norms is a more powerful correlate of sexual activity than gender role beliefs. The association between sexual norms and sexual experience is greater among young women than young men, and in less developed contexts compared to more developed contexts.
Condom attitudes have no significant association with condom use at first sex for any of the six groups. Attitudes towards condoms are a significant factor in condom use at last sex among young men in Taipei only. Condom use at first sex is the most salient factor in condom use at last sex, but this relationship varies by city and sex group.
Conclusions
This dissertation provides an in-depth and cross-cultural analysis of the respective influences of gender role beliefs, sexual norms and condom attitudes on sexual activity and condom use among youth in Hanoi, Shanghai and Taipei. While both gender and sexual norms are important factors in sexual activity, condom attitudes play less of a role in shaping condom use patterns. By highlighting the differences and commonalities in how knowledge, attitudes and beliefs and the relationship of each to sexual behaviors differ among male and female youth in three different Asian settings, this dissertation provides a basis for responding to Asian youth’s sexual and reproductive health needs
Facilitators and Barriers to Healthy Eating Among American Indian and Alaska Native Adults with Type 2 Diabetes: Stakeholder Perspectives
Background: American Indian and Alaska Native (AI/AN) adults have a higher prevalence of type 2 diabetes (T2D) and related complications than non-AI/AN adults. As healthy eating is a cornerstone of diabetes self-management, nutrition education plays an important role in diabetes self-management education.
Objective: To understand stakeholder perspectives on facilitators and barriers to healthy eating for AI/AN adults with T2D in order to inform the cultural adaptation of an existing diabetes nutrition education curriculum.
Methods: Individual interviews were conducted with 9 national content experts in diabetes nutrition education (e.g. registered dietitians, diabetes educators, experts on AI/AN food insecurity) and 10 community-based key informants, including tribal health administrators, nutrition/diabetes educators, Native elders, and tribal leaders. Four focus groups were conducted with AI/AN adults with T2D (n = 29) and 4 focus groups were conducted with their family members (n = 22). Focus groups and community-based key informant interviews were conducted at 4 urban and reservation sites in the USA. Focus groups and interviews were recorded and transcribed verbatim. We employed the constant comparison method for data analysis and used Atlas.ti (Mac version 8.0) to digitalize the analytic process.
Results: Three key themes emerged. First, a diabetes nutrition education program for AI/ANs should accommodate diversity across AI/AN communities. Second, it is important to build on AI/AN strengths and facilitators to healthy eating (e.g. strong community and family support systems, traditional foods, and food acquisition and preparation practices). Third, it is important to address barriers to healthy eating (e.g. food insecurity, challenges to preparation of home-cooked meals, excessive access to processed and fast food, competing priorities and stressors, loss of access to traditional foods, and traditional food-acquisition practices and preparation) and provide resources and strategies for mitigating these barriers. Conclusions: Findings were used to inform the cultural adaptation of a nutrition education program for AI/AN adults with T2D. Curr Dev Nutr 2021;5:nzaa114

Association of Highly Restrictive State Abortion Policies With Abortion Rates, 2000-2014
Importance: Although abortion is common in the United States, patients face substantial barriers to obtaining an abortion. Recently enacted abortion restrictions pose such barriers. Objectives: To assess the association between a state legislative climate that is highly restrictive toward abortion provision and the abortion rate and to evaluate whether distance to a facility providing abortion care mediates the association between legislative climate and the abortion rate. Design, Setting, and Participants: This cohort study examined county-of-residence abortion rates from all states that publicly provided them and used data on abortion restrictions, facility locations, and county demographic characteristics for the years 2000 to 2014. The association between legislative climate and abortion rates was evaluated using propensity score-weighted, linear regression difference-in-difference analysis. All models included state and year fixed effects and standard errors adjusted for state-level clustering. Exposures: Highly restrictive legislative climate, defined as having at least 3 of 4 types of abortion restrictions; distance to a high-volume facility providing abortion care (ie, performing ≥395 abortions per year) in miles. Main Outcomes and Measures: County-level abortion rate, defined as abortions per 1000 women per year. Results: Abortion rate data were obtained from 1178 counties in 18 states for a median of 12.5 years (range, 5-14). The median abortion rate was 2.89 per 1000 women (interquartile range, 1.71-4.46 per 1000 women). A highly restrictive legislative climate, when compared with a less restrictive one, was associated with 0.48 fewer abortions per 1000 women (95% CI, -0.92 to -0.04 abortions per 1000 women; P =.03). Adjusted for distance to a facility providing abortion care, a highly restrictive legislative climate was associated with 0.44 fewer abortions per 1000 women (95% CI, -0.85 to -0.03; P =.04). Each mile to a facility was associated with 0.02 fewer abortions per 1000 women (95% CI, -0.03 to -0.01 abortions per 1000 women; P =.003). Legislative climate was not significantly associated with distance to a facility providing abortion care (change in distance associated with highly restrictive climate, -2.73 [95% CI, -6.02 to 0.57] miles; P =.10). Conclusions and Relevance: This study provides evidence that a state legislative climate that is highly restrictive toward abortion provision is associated with a lower abortion rate. The cumulative effect of restrictive policies may pose a barrier to abortion access.</p
Teens Reflect on Their Sources of Contraceptive Information
Based on semistructured interviews with a racially and ethnically diverse sample of 58 U.S. high school students, this study examines teens’ exposure to contraceptive information from a range of sources and the extent to which they trust this information. Teens report exposure to contraceptive information from many individuals and places, most commonly school, family, and friends. Few teens rely on the Internet for contraceptive information, and most are wary of this source. The authors identify two themes that characterized teens’ discussions: wariness about hormonal methods, and the compatibility of contraception and abstinence messages. The findings suggest ways that schools, a common and trusted source of sexual health information for teens, could better improve students’ access to accurate contraceptive information. </jats:p
Understanding young women’s experiences of gender inequality in Lucknow, Uttar Pradesh through story circles
Gender inequality poses grave consequences for young women’s health and wellbeing. The aim of this study was to understand how gender influences the lives of young women living in urban slums of Lucknow, Uttar Pradesh, India using story circles as a research methodology. Narrative-based participatory methods like story circles (which involves sharing individual stories in a group circle on a given topic) can provide the nuance and detail needed to understand young people’s experiences, build trust between participants and researchers, and offer spaces to speak about culturally sensitive subjects. Six story circle sessions were conducted with 50 young women (aged 15–24) in Lucknow. Sessions were audio-recorded, transcribed, and coded. Transcriptions were analysed to identify the following salient themes, all of which act as mechanisms of gender inequality: mobility restrictions, rampant sexual harassment in the community, limited educational and work opportunities, and the utmost prioritization of marriage for young women

Diabetes and health-related quality of life among American Indians: the role of psychosocial factors.
PurposeLittle is known about the association of psychosocial factors with health-related quality of life (HRQoL) among American Indians with type 2 diabetes (T2D). This study described functional social support, emotional support, coping, resilience, post-traumatic stress disorder, and HRQoL, among American Indians by diabetes status and, among those with diabetes, examined the association of these factors with HRQoL.MethodsUsing data from the Cherokee Nation Health Survey collected between 2017 and 2019, we evaluated differences in each measure of interest according to diabetes status, using t-test and Chi-squared tests of association. We used weighted multiple logistic regression to examine associations between multiple psychosocial factors and HRQoL among those with diabetes.ResultsCompared to individuals without diabetes, participants with diabetes rated their functional social support (4.62 vs. 4.56, respectively) and coping (2.65 vs. 2.61, respectively) slightly lower and were more likely to report ≥ 15 days of poor physical (14% vs. 26%, respectively) and mental health (14% vs. 17%, respectively) in the past month. Odds of reporting poor overall health increased more than sixfold for those who were dissatisfied/very dissatisfied with life (AOR = 6.70). Resilience scores reduced odds of reporting ≥ 15 days with poor physical health, while experiences of post-traumatic stress doubled these odds.ConclusionOur study yielded insights into the risk as well as protective factors associated with diabetes outcomes in a large sample of American Indians with T2D. Researchers should design pragmatic trials that deepen understanding of preventive as well as treatment leverage through greater attention to experiences that compromise HRQoL
