A Multimodal Qualitative Approach to Understanding Menstrual Health Equity among Adolescents and Young Adults.

STUDY OBJECTIVE: Menstrual inequity-unequal access to menstrual health care or products-negatively affects well-being in relation to the menstrual cycle, a construct known as menstrual health. Few studies have explored menstrual inequities among adolescent and young adult populations in the United States. This multimodal qualitative research aimed to explore factors that influence the lived experience of menstruation among this population. METHODS: This qualitative study consisted of individual interviews among menstruators ages 13-24, recruited from an urban academic medical center. Participants (N = 20) were a mean age of 19 years; 25% previously endorsed period poverty, and 90% were publicly insured. We conducted semi-structured interviews using participant video diaries in a video elicitation exercise. Data were coded by 2 investigators using thematic analysis driven by grounded theory. RESULTS: Emergent themes included the need to normalize menstruation, the need for comprehensive menstrual health education, and the need for menstrual products to be more accessible. Twelve youth prepared video diaries, and all reported positive experiences with the video process. CONCLUSIONS: This youth-centered, multimodal study is one of the first to qualitatively explore the lived experiences of menstruation among adolescents in the United States and identified key inequities in menstrual health from their own perspectives. Thematic findings were mapped onto a proposed framework for menstrual equity that can be applied to future research and efforts around policy change. More research is needed to assess the impacts of these policies.

Adolescent Perceptions of Menstruation on Twitter: Opportunities for Advocacy and Education.

PURPOSE: While some adolescents celebrate menstruation as a rite of passage, others seek discretion due to stigma. Many youth have used Twitter to combat stigma and raise awareness about other culturally taboo topics, but previous work has not explored youth conversations regarding menstruation. This study aims to assess whether Twitter can provide useful insights into how youth perceive menstruation. METHODS: The team searched 162,316,839 tweets of 71,443 users of the age range 13-25 years in the Health Language Processing Twitter Youth Cohort for tweets that matched menstruation-related keywords: a pad, my pad, my period, her period, your period, tampon, diva cup, menstruate, that time of the month. Twelve codes emerged using a grounded theory approach and were sorted into three themes. RESULTS: Analysis was conducted on 10,000 tweets. Three themes emerged, including menstrual health, menstrual stigma, and menstrual positivity. Tweets related to menstrual health included physical complications, sexual/reproductive health, health education, and LGBTQ health. Tweets that addressed menstrual stigma included inconvenience/limitations, shame/stereotypes, religion/alternate perceptions, access/affordability, and self-depreciation/harm. Tweets related to menstrual positivity included awareness/community, strength/resilience, and environment/sustainability. DISCUSSION: This study provides insights into youth perceptions about menstruation. There was overwhelming emphasis placed on the negative expectations and shame around menstruation. A significant minority of tweets were directly or indirectly related to advocacy or education, which supports the potential use of Twitter as a platform to improve public health messaging, transform health outcomes, and promote equity among youth who menstruate.

Trends in health behavior and weight outcomes following enhanced afterschool programming participation.

BACKGROUND: The United States needs to increase access to effective obesity prevention and treatment programming for impoverished youth at risk for health disparities. Although recommended, schools have difficulty consistently implement evidence-based obesity programing. We report on the effectiveness of adding structured nutrition education and minimum physical activity (PA) requirements to standard middle school after-school programming. METHODS: Using a longitudinal pre-post study design, we evaluated program effectiveness at one year on target behaviors on students recruited during three consecutive school years (2016-2018). We used generalized linear (or logistic) mixed-effects modeling to determine: 1) impact on healthy weight and target healthy behavior attainment, and 2) whether target behavior improvement and weight change were associated with after-school program attendance. The seven target behaviors relate to eating healthy, physical activity, and sleep. RESULTS: Over the three years, a total of 76 students enrolled and completed one year of programming (62% Hispanic, 46% girls, 72% with BMI > 85th %ile, 49% with BMI > 95th %ile). Of students with BMI > 85th %ile, 44% maintained or decreased BMI Z-score. There were improvements (non-significant) in BMI Z-score and the adoption of four healthy eating behaviors: fruit, vegetables, sugar-free beverages, and unhealthy snack food. Students with higher after-school attendance (> 75%) had greater improvements (non-significant) in composite behavior scores, BMI Z-score, and in most target behaviors (5/7) than students with lower after-school attendance (< 75%). Sleep improvements were significantly associated with BMI Z-score decrease (Beta = - 0.05, 95% CI (- 0.1,-0.003), p = 0.038.) CONCLUSIONS: Enhancement of existing after-school programming with structured nutrition education and minimum physical activity requirements demonstrates positive improvements in several health behaviors and weight outcomes. Adopting enhanced after-school programming increases access to health activities and may bring us closer to solving obesity in at-risk youth in impoverished communities.

Powder cocaine and crack use in the United States: an examination of risk for arrest and socioeconomic disparities in use.

BACKGROUND: In light of the current sentencing disparity (18:1) between crack and powder cocaine possession in the United States, we examined socioeconomic correlates of use of each, and relations between use and arrest, to determine who may be at highest risk for arrest and imprisonment. METHODS: We conducted secondary data analyses on the National Survey on Drug Use and Health, 2009-2012. Data were analyzed for adults age ≥ 18 to determine associations between use and arrest. Socioeconomic correlates of lifetime and annual use of powder cocaine and of crack were delineated using multivariable logistic regression and correlates of frequency of recent use were examined using generalized negative binomial regression. RESULTS: Crack users were at higher risk than powder cocaine users for reporting a lifetime arrest or multiple recent arrests. Racial minorities were at low risk for powder cocaine use and Hispanics were at low risk for crack use. Blacks were at increased risk for lifetime and recent crack use, but not when controlling for other socioeconomic variables. However, blacks who did use either powder cocaine or crack tended to use at higher frequencies. Higher education and higher family income were negatively associated with crack use although these factors were sometimes risk factors for powder cocaine use. CONCLUSIONS: Crack users are at higher risk of arrest and tend to be of lower socioeconomic status compared to powder cocaine users. These findings can inform US Congress as they review bills (e.g., The Smarter Sentencing Act), which would help eliminate cocaine-related sentencing disparities.

A review of air quality, biological indicators and health effects of second-hand waterpipe smoke exposure.

OBJECTIVE: There has been a rapid increase in the use of waterpipe tobacco and non-tobacco based shisha in many countries. Understanding the impact and effects of second-hand smoke (SHS) from cigarette was a crucial factor in reducing cigarette use, leading to clean indoor air laws and smoking bans. This article reviews what is known about the effects of SHS exposure from waterpipes. DATA SOURCES: We used PubMed and EMBASE to review the literature. Articles were grouped into quantitative measures of air quality and biological markers, health effects, exposure across different settings, different types of shisha and use in different countries. STUDY SELECTION: Criteria for study selection were based on the key words related to SHS: waterpipe, hookah, shisha and third-hand smoke. DATA EXTRACTION: Independent extraction with two reviewers was performed with inclusion criteria applied to articles on SHS and waterpipe/hookah/shisha. We excluded articles related to pregnancy or prenatal exposure to SHS, animal studies, and non-specific source of exposure as well as articles not written in English. DATA SYNTHESIS: A primary literature search yielded 54 articles, of which only 11 were included based on relevance to SHS from a waterpipe/hookah/shisha. CONCLUSIONS: The negative health consequences of second-hand waterpipe exposure have major implications for clean indoor air laws and for occupational safety. There exists an urgent need for public health campaigns about the effects on children and household members from smoking waterpipe at home, and for further development and implementation of regulations to protect the health of the public from this rapidly emerging threat.

Manipulation of Fgf and Bmp signaling in teleost fishes suggests potential pathways for the evolutionary origin of multicuspid teeth.

Teeth with two or more cusps have arisen independently from an ancestral unicuspid condition in a variety of vertebrate lineages, including sharks, teleost fishes, amphibians, lizards, and mammals. One potential explanation for the repeated origins of multicuspid teeth is the existence of multiple adaptive pathways leading to them, as suggested by their different uses in these lineages. Another is that the addition of cusps required only minor changes in genetic pathways regulating tooth development. Here we provide support for the latter hypothesis by demonstrating that manipulation of the levels of Fibroblast growth factor (Fgf) or Bone morphogenetic protein (Bmp) signaling produces bicuspid teeth in the zebrafish (Danio rerio), a species lacking multicuspid teeth in its ancestry. The generality of these results for teleosts is suggested by the conversion of unicuspid pharyngeal teeth into bicuspid teeth by similar manipulations of the Mexican Tetra (Astyanax mexicanus). That these manipulations also produced supernumerary teeth in both species supports previous suggestions of similarities in the molecular control of tooth and cusp number. We conclude that despite their apparent complexity, the evolutionary origin of multicuspid teeth is positively constrained, likely requiring only slight modifications of a pre-existing mechanism for patterning the number and spacing of individual teeth.
