Understanding Public Perceptions of Per- and Polyfluoroalkyl Substances: Infodemiology Study of Social Media.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are environmental contaminants that have received significant public attention. PFAS are a large group of human-made chemicals that have been used in industry and consumer products worldwide since the 1950s. Human exposure to PFAS is a growing public health concern. Studies suggest that exposure to PFAS may increase the risk of some cancers and have negative health impacts on the endocrine, metabolic, and immune systems. Federal and state health partners are investigating the exposure to and possible health effects associated with PFAS. Government agencies can observe social media discourse on PFAS to better understand public concerns and develop targeted communication and outreach efforts. OBJECTIVE: The primary objective of this study is to understand how social media is used to share, disseminate, and engage in public discussions of PFAS-related information in the United States. METHODS: We investigated PFAS-related content across 2 social media platforms between May 1, 2017, and April 30, 2019, to identify how social media is used in the United States to seek and disseminate PFAS-related information. Our key variable of interest was posts that mentioned "PFAS," "PFOA," "PFOS," and their hashtag variations across social media platforms. Additional variables included post type, time, PFAS event, and geographic location. We examined term use and post type differences across platforms. We used descriptive statistics and regression analysis to assess the incidence of PFAS discussions and to identify the date, event, and geographic patterns. We qualitatively analyzed social media content to determine the most prevalent themes discussed on social media platforms. RESULTS: Our analysis revealed that Twitter had a significantly greater volume of PFAS-related posts compared with Reddit (98,264 vs 3126 posts). PFAS-related social media posts increased by 670% over 2 years, indicating a marked increase in social media users' interest in and awareness of PFAS. Active engagement varied across platforms, with Reddit posts demonstrating more in-depth discussions compared with passive likes and reposts among Twitter users. Spikes in PFAS discussions were evident and connected to the discovery of contamination events, media coverage, and scientific publications. Thematic analysis revealed that social media users see PFAS as a significant public health concern and seek a trusted source of information about PFAS-related public health efforts. CONCLUSIONS: The analysis identified a prevalent theme-on social media, PFAS are perceived as an immediate public health concern, which demonstrates a growing sense of urgency to understand this emerging contaminant and its potential health impacts. Government agencies can continue using social media research to better understand the changing community sentiment on PFAS and disseminate targeted information and then use social media as a forum for dispelling misinformation, communicating scientific findings, and providing resources for relevant public health services.

Postnatal care by provider type and neonatal death in sub-Saharan Africa: a multilevel analysis.

BACKGROUND: Globally postnatal care (PNC) of the newborn is being promoted as a strategy to reduce neonatal deaths, yet few studies have looked at associations between early PNC and neonatal outcomes in sub-Saharan Africa. In this study we look at the associations of PNC provided on day 1 and by day 7 of life by type of provider - skilled (doctor, midwife or nurse or unskilled (traditional birth attendant or community health worker) on neonatal death on days 2 to 7 and days 2 to 28. METHODS: Data from 10 African countries with recent (from 2009 onwards) Demographic and Health Surveys are pooled and used in a multilevel logistic regression analysis to study associations between the PNC variables with the mortality outcomes after controlling for relevant socioeconomic and maternal factors (including antenatal care, skilled delivery, tetanus immunization and ever breastfed). RESULTS: Findings indicate that PNC, whether provided by a skilled or unskilled provider, is protective against both neonatal death outcomes. Unskilled PNC on day 1 was associated with a 32% decrease in the probability of death (compared to no PNC on day 1) during days 2 to 28 after controlling for other factors (OR: 0.68; 95% CI: 0.48, 0.97). Both skilled and unskilled PNC by day 7 were associated with reduced neonatal death during days 2 to 7 (Skilled: OR: 0.40; 95% CI 0.18, 0.88; Unskilled: OR 0.34; 95% CI 0.23, 0.52) and days 2 to 28 (Skilled: OR: 0.51; 95% CI 0.35, 0.75; Unskilled: OR 0.34; 95% CI 0.30, 0.38). There were also significant associations between four or more antenatal care visits and ever breastfed with both outcomes. CONCLUSION: PNC is an important strategy to reduce neonatal death. While postnatal care by a skilled provider is a preferred strategy, PNC provided by unskilled providers can also serve as an intermediate implementation approach as countries strive to reach more newborns and save more lives.

One size does not fit all: psychometric properties of the Shona Symptom Questionnaire (SSQ) among adolescents and young adults in Zimbabwe.

BACKGROUND: Depression is a major contributor to the global burden of disease. Onset commonly occurs during the adolescent period. Understanding how depression tools are functioning among adolescents has been relatively overlooked. METHODS: Using cross-sectional survey data among a sample of 2768 adolescents (aged 15-19) and 2027 young adults (aged 20-24) living in Zimbabwe this paper calibrated the Shona Symptom Questionnaire (SSQ) against the Self Report Questionnaire (SRQ-20) and examined the performance indices of the SSQ based on various cut points for classification. Using a multivariate logistic regression model we isolated particular characteristics to test their association with the odds of being misclassified as non-depressed by the SSQ. RESULTS: A modified cut point of five or more substantially increases the depression estimates for both age groups. The prevalence of depression increased from 3.5% to 13.2% among adolescents and from 5.1% to 16.2% among young adults based on these revisions. Adolescents who were orphaned or ever had sex had significantly a greater odd of being misclassified. When retested using the modified cut point of five or greater, associations with misclassification disappeared. LIMITATIONS: Scales were not administered separately or in their entirety but rather overlapping items were only asked once, utilizing exclusively SRQ-20 phrasing rather than the culturally-emic language in the SSQ. CONCLUSIONS: Not all depression scales are appropriate for use among adolescents given their unique developmental stage. An alternative cut point for depression classification could improve detection of depression among Zimbabwean adolescents.

Gender differences in HIV disclosure, stigma, and perceptions of health.

HIV disclosure is a gateway to HIV prevention - particularly among couples living in regions severely affected by the HIV epidemic. This cross-sectional study utilizes data collected from 862 people living with HIV across three countries (Ethiopia, Mozambique, and Uganda) in 2011 to determine the role of partner disclosure on self-reported health perceptions and changes in sexual risk behavior. The study's secondary aims are to understand whether or not internalized stigma mediates this relationship and if there is a different pattern of results by gender. The multivariate analysis reveals that the three key HIV-related independent variables, belonging to a support group, doing volunteer work, and disclosing to one's spouse or partner, were significantly associated with lower levels of internalized stigma. Internalized stigma was associated with self-perceptions of poorer health for both women and men, with women reporting higher levels of internalized stigma than men. Disclosure to spouse was positively associated with perceptions of better health for women but not for men. For men, doing HIV-related volunteer work and disclosing their status to their spouse were positively associated with self-reported changes in sexual risk behavior, although stigma was not found to mediate this relationship. Findings from this study suggest that disclosure and stigma have gender-specific effects on individual well-being and changes in sexual risk behaviors. As such, programs must address gender inequity in disclosure patterns and stigma to enhance prevention efforts.

Gender equality and education: Increasing the uptake of HIV testing among married women in Kenya, Zambia and Zimbabwe.

Gender equality and education are being promoted as strategies to combat the HIV epidemic in Africa, but few studies have looked at the role of gender equality and education in the uptake of a vital service - HIV testing. This study looks at the associations between education (a key input needed for gender equality) and key gender equality measures (financial decision making and attitudes toward violence) with ever tested for HIV and tested for HIV in the past year. The study focused on currently married women ages between15-24 and 25-34 in three countries - Kenya, Zambia, and Zimbabwe. The data came from the Demographic and Health Surveys. Logistic regression was used to study the role of gender equality and education on the HIV testing outcomes after controlling for both social and biological factors. Results indicated that education had a consistent positive relationship with testing for both age groups, and the associations were always significant for young women aged 15-24 years (p<0.01). The belief that gender-based violence is unacceptable was positively associated with testing for women aged 25-34 in all the three countries, although the associations were only significant in Kenya (among women reporting ever being tested: OR 1.58, p<0.00; among women reporting being tested in the past year: OR 1.34, p<0.05) and Zambia (among women reporting ever being tested: OR 1.24, p<0.10; among women reporting being tested in the past year: OR 1.29, p<0.05). High financial decision making was associated with testing for women aged 25-34 in Zimbabwe only (among women reporting ever being tested: OR 1.66, p<0.01). Overall, the findings indicate that the education and the promotion of gender equality are important strategies for increasing uptake of a vital HIV service, and thus are important tools for protecting girls and young women against HIV.

Maternal autonomy and attitudes towards gender norms: associations with childhood immunization in Nigeria.

Globally 2.5 million children under-five die from vaccine preventable diseases, and in Nigeria only 23 % of children ages 12-23 months are fully immunized. The international community is promoting gender equality as a means to improve the health and well-being of women and their children. This paper looks at whether measures of gender equality, autonomy and individual attitudes towards gender norms, are associated with a child being fully immunized in Nigeria. Data from currently married women with a child 12-23 months from the 2008 Nigeria demographic and health survey were used to study the influence of autonomy and gender attitudes on whether or not a child is fully immunized. Multivariate logistic regression was used and several key socioeconomic variables were controlled for including wealth and education, which are considered key inputs into gender equality. Findings indicated that household decision-making and attitudes towards wife beating were significantly associated with a child being fully immunized after controlling for socioeconomic variables. Ethnicity, wealth and education were also significant factors. Programmatic and policy implications indicate the potential for the promotion of gender equality as a means to improve child health. Gender equality can be seen as a means to enable women to access life-saving services for their children.

The importance of HIV prevention messaging for orphaned youth in Zimbabwe.

The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Female adolescent orphans are particularly in jeopardy of contracting HIV due to disadvantages including extreme poverty, low education, and the absent of parental oversight which can lead to higher risk-taking sexual behaviors. By understanding where girls receive education about HIV and who they rely on for information, organizations can effectively modify existing programs to better target this at-risk population. For this study a household survey was conducted which included 216 orphans and 324 non-orphans (n=540), aged 12-17 years, in the resource-poor setting of Hwange District, Zimbabwe. The aims of this article were to examine the differences between orphans and non-orphans in HIV prevention message exposure, level of motivation for learning about HIV, and communication with caregivers about safe sex. The household survey revealed that younger orphans, aged 12-15 years, were more motivated to learn about HIV and had greater HIV messaging exposure in school than non-orphans. These exposure and differences in the levels of motivation between groups dissipated at older ages. Our research also discovered less caregiver communication among orphans than non-orphans. Our findings suggest that HIV programs targeting orphans need to do a better job at keeping older orphans interested in HIV prevention at a time when it matters most. Furthermore, intervention strategies that provide caregiver support are instrumental in effectively delivering prevention messages to girls at home.

Gender equality and childbirth in a health facility: Nigeria and MDG5.

This paper examined how addressing gender equality can lead to reductions in maternal mortality in Nigeria through an increased use of facility delivery. Because the majority of maternal complications cannot be predicted and often arise suddenly during labor, delivery and the immediate postpartum period, childbirth in a health facility is key to reducing maternal mortality. This paper used data from the 2008 Nigeria Demographic and Health Survey (DHS) to examine associations of gender measures on the utilization of facility delivery after controlling for socio-demographic factors. Four gender equality measures were studied: household decision-making, financial decision-making, attitudes towards wife beating, and attitudes regarding a wife's ability to refuse sex. Results found older, more educated, wealthier, urban, and working women were more likely to have a facility delivery than their counterparts. In addition ethnicity was a significant variable indicating the importance of cultural and regional diversity. Notably, after controlling for the socioeconomic variables, two of the gender equality variables were significant: household decision-making and attitudes regarding a wife's ability to refuse sex. In resource-poor settings such as Nigeria, women with more decision-making autonomy are likely better able to advocate for and access a health facility for childbirth. Thus programs and policies that focus on gender in addition to focusing on education and poverty have the potential to reduce maternal mortality even further.
