A Comparison of Alternative Tobacco Product Usage, Knowledge and Beliefs Between the New York City Lesbian, Gay, Bisexual, and Transgendered Community and Heterosexuals.

Within the United States, alternative tobacco product (ATP) and varies by geographic region, gender and age. Few articles have been published on the usage of these products among the lesbian, gay, bisexual, transgender or queer (LGBTQ) population. A web-based anonymous survey administered through Google Forms, was used to collect data on current tobacco usage, knowledge and beliefs from adult heterosexuals, homosexuals, bisexuals and transgendered persons residing in New York City from May 2014 to July 2014. Sixty-four individuals completed the survey; 30 were heterosexual and 32 identified as either lesbian, gay, bisexual, transgender or queer. Heterosexuals were found to have tried cigarettes, on average, almost a year before the LGBTQ respondents. Social networks were influential to LGBTQ respondents for an introduction to smoking; 48.00% were introduced by friends, 28.00% by family, 12.00% by a significant other and 9.09% by someone else. For heterosexuals, 73.68% reported that friends introduced them to smoking. More heterosexuals reported trying hookah (N = 10), snus (N = 4) and roll your own cigarettes (N = 5). On average respondents knew of eight different tobacco products, regardless of sexual identity. To our knowledge, we present for the first time a comparison of people who tried, current and former users of ATPs, beliefs and knowledge about ATPs, and sources of knowledge of ATPs by sexual identity from NYC. More research is needed to examine the impact of social networks and the upcoming FDA regulations on ATPs have on the overall prevalence of usage among the LGBTQ community.

Fetal sex and race modify the predictors of fetal growth.

The objective of this study is unknown if fetal sex and race modify the impact of maternal pre-pregnancy body mass index (BMI), and smoking on fetal growth. The authors studied markers of fetal growth in singleton offspring of 8,801 primiparous, normotensive women, enrolled in the Collaborative Perinatal Project. The authors tested for departures from additivity between sex/race and each predictor. The head-to-chest circumference ratio (HCC) decreased more, while birthweight and ponderal index (PI) increased more for each 1 kg/m(2) increase in pre-pregnancy BMI among term females versus males (P = 0.07, P < 0.01 and P = 0.08, interaction respectively). For term offspring of White compared with Black women, smoking independent of "dose" was associated with larger reductions in growth (165 g vs. 68 g reduction in birthweight, P < 0.01, interaction), greater reduction in fetal placental ratio (P < 0.01, interaction), PI (P < 0.01, interaction), and greater increase in HCC (P = 0.02), respectively. The association of BMI and smoking with fetal size appeared to be reversed in term versus preterm infants. Our study provides evidence that the associations of pre-pregnancy BMI and smoking are not constant across sex and race. This finding may be relevant to sex and race differences in neonatal and long term health outcomes.

Association between Urinary Triclosan and Serum Testosterone Levels in U.S. Adult Males from NHANES, 2011-2012.

Triclosan was introduced into the market in the 1970s and has since been used as an antimicrobial agent in a diverse array of consumer and personal care products. Although it has been widely used over a number of years, there is growing concern and debate over its safety and efficacy and its potential as an endocrine disruptor. Although prior animal toxicology studies have shown an association between triclosan and decreased testosterone levels, human studies have been limited, particularly for adult men. Using the National Health and Nutrition Examination Survey data (NHANES, 2011-2012), we examined the association of urinary triclosan on testosterone levels in adult men 18-65 years of age. Multivariable linear regression analysis failed to show an association between triclosan and serum testosterone (ß = 0.0003, p = 0.98, 95% CI = -0.024, 0.025). The results suggest there is no association or that triclosan concentrations are too low to cause a significant impact on testosterone levels. Additionally, longitudinal studies would provide a more comprehensive understanding of the direction of change and magnitude of causal relationships over time.

Stress, Socializing, and Other Motivations for Smoking Among the Lesbian, Gay, Bisexual, Transgender, and Queer Community in New York City.

PURPOSE: This study contributes to the emerging literature on lesbian, gay, bisexual, transgendered, and queer (LGBTQ) health disparities and tobacco use by examining the motivations for smoking among the New York City (NYC) LGBTQ population. APPROACH: We used grounded theory and blended methods from 3 grounded theorists-Strauss, Corbin, and Charmaz-for data collection, coding, and analysis. SETTING: NYC has extensive legislation to prevent smoking; however, the current smoking prevalence of homosexuals is double that of heterosexuals. PARTICIPANTS: Study participants were leaders from 23 NYC LGBTQ organizations. Leaders were chosen to establish a relationship with community and to ensure cultural sensitivity. Eligibility criteria required holding a leadership position in an organization serving the NYC LGBTQ community. METHODS: Interviews were transcribed verbatim and uploaded into Dedoose for analysis. An initial code list was developed from the interview guide. Key themes were identified as the themes with the most number of quotes. RESULTS: Three key themes emerged from our interviews: image, socializing, and stress. Smoking was reported to be a socialization aid and a maladaptive coping technique for stress arising from interactions of conflicting identities. CONCLUSION: Future smoking cessation interventions among the LGBTQ community should equip smokers with healthy coping mechanisms that address the stressors that arise from the intersections of smokers' many identities.

The National Children's Study: Recruitment Outcomes Using the Provider-Based Recruitment Approach.

OBJECTIVE: In 2009, the National Children's Study (NCS) Vanguard Study tested the feasibility of household-based recruitment and participant enrollment using a birth-rate probability sample. In 2010, the NCS Program Office launched 3 additional recruitment approaches. We tested whether provider-based recruitment could improve recruitment outcomes compared with household-based recruitment. METHODS: The NCS aimed to recruit 18- to 49-year-old women who were pregnant or at risk for becoming pregnant who lived in designated geographic segments within primary sampling units, generally counties. Using provider-based recruitment, 10 study centers engaged providers to enroll eligible participants at their practice. Recruitment models used different levels of provider engagement (full, intermediate, information-only). RESULTS: The percentage of eligible women per county ranged from 1.5% to 57.3%. Across the centers, 3371 potential participants were approached for screening, 3459 (92%) were screened and 1479 were eligible (43%). Of those 1181 (80.0%) gave consent and 1008 (94%) were retained until delivery. Recruited participants were generally representative of the county population. CONCLUSIONS: Provider-based recruitment was successful in recruiting NCS participants. Challenges included time-intensity of engaging the clinical practices, differential willingness of providers to participate, and necessary reliance on providers for participant identification. The vast majority of practices cooperated to some degree. Recruitment from obstetric practices is an effective means of obtaining a representative sample.

Newborns of preeclamptic women show evidence of sex-specific disparity in fetal growth.

BACKGROUND: Evidence suggests that in response to in utero insults, male versus female infants have greater disadvantages in pregnancy outcome. In addition, there is a growing body of evidence suggesting that there is a sex-specific fetal response to maternal disease during pregnancy. We considered that a sex-specific relationship may exist between preeclampsia and reduced fetal growth. OBJECTIVE: We investigated if the relationship between preeclampsia and fetal growth was modified by fetal sex. METHODS: We limited the study population to singleton pregnancies of black and white normotensive and preeeclamptic women enrolled in the Collaborative Perinatal Project (1959-1965). The patients were offspring of 516 preeclamptic and 8801 normotensive women. After adjustment for confounders, interaction terms between preeclamptic status and fetal sex were evaluated to determine if the influence of preeclampsia on fetal growth varied with fetal sex. Separate linear and logistic regression models were then fitted for males and females to report the estimate of the relationship between preeclampsia and fetal growth by fetal sex. The results were stratified by preterm status (<37 vs ≥37 completed weeks of gestation). The mean head and chest circumferences, birthweight, ponderal index, and frequency of small for gestational age were examined. A 2-sided P value of <0.05 was considered statistically significant. RESULTS: The results were stratified by preterm status. Male preterm offspring of preeclamptic mothers had greater reductions in chest circumference, head circumference, and birthweight than preterm female offspring of preeclamptic women (P = 0.01, P = 0.02, and P = 0.05, respectively, for interaction). Female versus male preterm offspring exposed to preeclampsia were less susceptible to being small for gestational age (synergy index 0.38; 95% CI, 0.00-0.84). The influence of preeclampsia on the growth of term offspring was more modest, and the influence of sex was opposite that in preterm infants. Compared with term offspring of normotensive women, the reduction in mean ponderal index was greater for female versus term male offspring of preeclamptic women (P = 0.02, interaction). CONCLUSION: Fetal growth was more impaired among male versus female preterm infants born to preeclamptic women. Our study underlined the importance of incorporating sex differences in the study of biological mechanisms for immediate- and long-term consequences of suboptimal fetal growth.
