Social Ecological Influences on Nicotine/Tobacco Use Among Gender-Varying and Gender-Stable Adolescents and Adults in the USA.

BACKGROUND AND PURPOSE: Our study examined individual-, interpersonal-, community-, and policy-level associations with nicotine/tobacco use among gender-varying and gender-stable U.S. individuals. METHODS: Data from Waves 2-4 (2014/15-2016/18) of the Population Assessment of Tobacco and Health (n = 33,197 U.S. adolescents and adults aged ≥14 years) and state-level gender minority policy data were used. Using multivariable logistic regression, the odds of past-30-day nicotine/tobacco use at W4 were estimated as a function of gender stability/variability, psychological distress, number of tobacco products used by family/friends, anti-tobacco marketing exposure, and change in gender minority-related policies from 2015 to 2017. RESULTS: Gender-varying individuals had higher odds of nicotine/tobacco use compared with gender-stable individuals (AOR range = 1.7-2.3, p < .01). In the overall sample, positive change in gender minority policy protections (tallied from medium to high) was associated with lower odds of any nicotine/tobacco, other tobacco, and poly-tobacco use (AOR = 0.8, p < .05) compared to states with no change in their negative policies. Anti-tobacco marketing exposure was associated with lower odds of any tobacco, cigarette, e-cigarette, and poly-tobacco use compared with those who had no anti-tobacco marketing exposure (AOR = 0.9, p < .05). Higher psychological distress (AOR range = 1.7-2.4, p < .001) and an increasing number of tobacco products used by family/friends (AOR range = 1.1-1.3, p < .001) were associated with increased odds of nicotine/tobacco use. CONCLUSIONS: Multilevel prevention and intervention strategies are needed to reduce the risk of nicotine/tobacco use among gender-varying and gender-stable individuals.

Prior work has shown that individuals whose gender identity changes over time (i.e., gender-varying) have higher risk for nicotine/tobacco use compared with individuals whose gender identity remains consistent over time (i.e., gender-stable). This study examined individual-, interpersonal-, community-, and policy-level associations with nicotine/tobacco use among gender-varying and gender-stable U.S. adolescents and adults. We analyzed data from Waves 2­4 (2014/15­2016/18) of the Population Assessment of Tobacco and Health study (n = 33,197 U.S. adolescents and adults aged 14 years and above) and state-level gender identity policy data from the Movement Advancement Project. Among the overall sample, we found that a positive change in state-level policy protections was associated with lower odds of any nicotine/tobacco, other tobacco, and poly-tobacco use compared with states that had no change in their negative policies. Exposure to anti-tobacco marketing was associated with lower odds of any tobacco, cigarette, e-cigarette, and poly-tobacco use compared with those who had no exposure to anti-tobacco marketing. Higher psychological distress and an increasing number of tobacco products used by close friends and family were associated with increased odds of nicotine/tobacco use. Multilevel prevention and intervention strategies are needed to reduce the risk of nicotine/tobacco use among gender-varying and gender-stable individuals.

How a "Something Else" Response Option for Sexual Identity Affects National Survey Estimates of Associations Between Sexual Identity, Reproductive Health, and Substance Use.

This randomized experiment tested whether the inclusion of a "something else" response option for a question about sexual identity in a national health survey would significantly moderate estimated differences between sexual identity subgroups in terms of various health outcomes, including substance use and reproductive health. We conducted secondary analyses of data from five consecutive years of the National Survey of Family Growth (NSFG; 2015-2019), where two large national half-samples were randomly assigned to receive one of two different versions of a question about sexual identity (a four-category version that included a "something else" response option or a three-category version omitting this option). We focused on national estimates of differences between subgroups defined by sexual identity. Multivariable models indicated that the estimated subgroup differences changed in a statistically significant fashion when using the four-category version of the sexual identity question for several measures, including 16% of male measures (household size, past-year cigarette use, and past-year illicit drug use) and 15% of female measures (wanting a/another child, ever had a sexually transmitted disease, and past-year marijuana use). The absence of a "something else" response option for questions about sexual identity in national health surveys may cause respondents to select options that do not accurately describe their identities, and this can have a significant effect on national estimates of differences between sexual identity subgroups in terms of selected health outcomes.

Forced intercourse in America: a pandemic update.

BACKGROUND: Measures of forced intercourse from the U.S. National Center for Health Statistics (NCHS) indicate high prevalence among U.S. women, which is likely to produce unintended pregnancies. However, NCHS did not measure forced intercourse during the pandemic, limiting knowledge of recent prevalence rates. METHODS: We use multiple nationally-representative, cross-sectional surveys representing the U.S. population from 2011 to 2022 to document these trends. This includes measures from the National Survey of Family Growth, the Panel Study of Income Dynamics Transition into Adulthood Supplement, and the American Family Health Study (AFHS) to provide population estimates of forced intercourse. RESULTS: Reports of forced intercourse remained high during the pandemic, with more than 25% of U.S. females over 40 reporting lifetime forced intercourse in the AFHS (number of females in AFHS: 1,042). There was a significant increase among females aged 24-28 (p < 0.05) and rates are highest for those who did not complete college. Among females 24-28, 32.5% (S.E. = 5.7%) with less than 4 years of college reported forced intercourse, a significantly (p < 0.05) higher rate than among those with a higher level of education. CONCLUSIONS: Rates of forced intercourse among U.S. women remained high during the pandemic, increasing significantly in early adulthood. This exposure to forced intercourse is likely to produce an increase in unintended pregnancies and other sexual, reproductive, and mental health problems.

Identifying latent classes of Relative Energy Deficiency in Sport (RED-S) consequences in a sample of collegiate female cross country runners.

OBJECTIVE: The purpose of this study was to identify patterns of clustering of the 10 health consequences identified in the Relative Energy Deficiency in Sport (RED-S) framework among collegiate female Cross-Country runners. We also assessed risk characteristics associated with each cluster. METHODS: This randomly sampled population included 211 current National Collegiate Athletics Association (NCAA) Division I (DI) female cross country runners who completed a quantitative survey. We used latent class analysis (LCA) to group athletes into mutually exclusive classes based on shared response patterns of RED-S consequences. We computed descriptive statistics to identify demographics, personal characteristics, disordered eating and emotional health characteristics associated with each class. RESULTS: The average age of the sample was 21 years with mean body mass index 20.4 kg/m2. The LCA identified three unique classes of potential RED-S presentations: (1) low probability of RED-S consequences; (2) complex physical and psychological concerns with a higher burden of cardiovascular concern and (3) very high probability of anxiety with high burden of menstrual disturbance, bone injury and gastrointestinal concern. All classes were characterised by high levels of menstrual disturbance and distinguished by the number and burden of other potential RED-S consequences and in reported abuse history, emotional regulation and perfectionism. CONCLUSION: This study identified a high burden of menstrual disturbance in NCAA D1 cross country runners, and three unique presentations of RED-S consequences. Future research is warranted to better understand how early prevention and intervention strategies may mitigate RED-S consequences in distance runners.

Tobacco Use Among Gender-Varying and Gender-Stable Adolescents and Adults Living in the United States.

INTRODUCTION: This study examines the proportion of the United States adolescents and adults who are variable (ie, at least one change in gender identity) versus stable in their gender identities over time, and whether they differ significantly in their nicotine/tobacco use after adjusting for key covariates. METHODS: We fit multivariable logistic regression models to data from Waves 2-4 (2014/15-2016/18) of the Population Assessment of Tobacco and Health (PATH), a nationally representative study (n = 33 197 U.S. adolescents and adults aged ≥14 years). We examined associations of gender stability/variability over three waves with tobacco use at wave 4 (2016-2018). Differences in any past 30-day tobacco, cigarette, e-cigarette, other tobacco, and poly-tobacco use were assessed among cisgender-stable, transgender-stable, and gender-varying respondents. RESULTS: An estimated 1.0% of adolescents and adults were classified as gender-varying. Prevalence of any past 30-day tobacco use was higher among gender-varying individuals (42.7%) than among gender-stable individuals (transgender-stable, 37.8% and cisgender-stable, 26.7%). There were no significant differences in the odds of nicotine/tobacco use between the two gender-stable groups. However, gender-varying respondents had significant increased odds of any past 30-day tobacco use (adjusted odds ratio [AOR] = 2.0, 95% confidence interval [CI] = 1.3 to 3.0), cigarette use (AOR = 1.7, 95% CI = 1.1 to 2.5), e-cigarette use (AOR = 2.2, 95% CI = 1.4-3.5), other tobacco use (AOR = 2.2, 95% CI = 1.4 to 3.4), and poly-tobacco use (AOR = 2.0, 95% CI = 1.3 to 3.1) compared with cisgender-stable individuals. CONCLUSIONS: Gender-varying individuals are at higher risk for nicotine/tobacco use, placing them at greater risk for tobacco-related health consequences. IMPLICATIONS: Despite increased knowledge about transgender health in recent years, there remains a paucity of research about gender-varying individuals. This study is the first to examine the proportion of gender-varying individuals in the United States using a longitudinal, nationally representative sample and to explore differences in nicotine/tobacco use among gender-varying and gender-stable individuals. Our findings suggest that gender-varying people have an increased risk for nicotine/tobacco use, placing them at higher risk for tobacco-related health consequences. This study increases knowledge about nicotine/tobacco use among this under-represented population in research and underscores the importance of developing an awareness of gender diversity.

Predictors of Smartphone and Tablet Use Among Patients With Hypertension: Secondary Analysis of Health Information National Trends Survey Data.

BACKGROUND: Uncontrolled hypertension leads to significant morbidity and mortality. The use of mobile health technology, such as smartphones, for remote blood pressure (BP) monitoring has improved BP control. An increase in BP control is more significant when patients can remotely communicate with their health care providers through technologies and receive feedback. Little is known about the predictors of remote BP monitoring among hypertensive populations. OBJECTIVE: The objective of this study is to quantify the predictors of smartphone and tablet use in achieving health goals and communicating with health care providers via SMS text messaging among hypertensive patients in the United States. METHODS: This study was a cross-sectional, secondary analysis of the 2017 and 2018 Health Information National Trends Survey 5, cycles 1 and 2 data. A total of 3045 respondents answered "Yes" to the question "Has a doctor or other healthcare provider ever told you that you had high blood pressure or hypertension?", which defined the subpopulation used in this study. We applied the Health Information National Trends Survey full sample weight to calculate the population estimates and 50 replicate weights to calculate the SEs of the estimates. We used design-adjusted descriptive statistics to describe the characteristics of respondents who are hypertensive based on relevant survey items. Design-adjusted multivariable logistic regression models were fitted to estimate predictors of achieving health goals with the help of smartphone or tablet and sending or receiving an SMS text message to or from a health care provider in the last 12 months. RESULTS: An estimated 36.9%, SE 0.9% (183,285,150/497,278,883) of the weighted adult population in the United States had hypertension. The mean age of the hypertensive population was 58.3 (SE 0.48) years. Electronic communication with the doctor or doctor's office through email or internet (odds ratio 2.93, 95% CI 1.85-4.63; P<.001) and having a wellness app (odds ratio 1.82, 95% CI 1.16-2.86; P=.02) were significant predictors of using SMS text message communication with a health care professional, adjusting for other demographic and technology-related variables. The odds of achieving health-related goals with the help of a tablet or smartphone declined significantly with older age (P<.001) and ownership of basic cellphones (P=.04). However, they increased significantly with being a woman (P=.045) or with being married (P=.03), having a wellness app (P<.001), using devices other than smartphones or tablets to monitor health (P=.008), making health treatment decisions (P=.048), and discussing with a provider (P=.02) with the help of a tablet or smartphone. CONCLUSIONS: Intervention measures accounting for age, gender, marital status, and the patient's technology-related health behaviors are required to increase smartphone and tablet use in self-care and SMS text message communication with health care providers.

Trends in binge drinking, marijuana use, illicit drug use, and polysubstance use by sexual identity in the United States (2006-2017).

Background: National studies often examine associations between sexual identity and substance use at a single point in time and neglect to examine whether these associations change over time. The present study examines U.S. trends in the past-year prevalence of binge drinking, marijuana use, illicit drug use, and polysubstance use across sexual identity subgroups (gay, lesbian, bisexual and heterosexual). Methods: The data come from four independent, cross-sectional samples measured by the National Survey of Family Growth (2006-2010, 2011-2013, 2013-2015, and 2015-2017). Based on the consistency in the sampling procedures used over time, merging the four data sets was possible. The target population is men and women 15-44 years of age. Results: Lesbian women had the sharpest decline in past-year binge drinking over time, followed by heterosexual women. The prevalence of binge drinking for bisexual women did not change significantly over time and was higher in 2015-2017 than for any sexual identity subgroup. In contrast, there were no significant differences in the prevalence of binge drinking among men by sexual identity subgroup. Past-year abstinence from substance use was consistently lower among lesbian women, gay men, and bisexual women relative to other sexual identity subgroups. Polysubstance use was consistently more prevalent among bisexual women (e.g., 32.3% in 2015-2017) as compared to other sexual identity subgroups. Conclusion: This is the first study to examine U.S. national trends in alcohol, marijuana, illicit drug, and polysubstance use across sexual identity subgroups, and demonstrates that sexual identity subgroup differences were robust with relatively few changes in trends over time. The consistently high rates of binge drinking and polysubstance use among bisexual women deserve much closer attention based on the related health consequences.

Is it all in the family? Sexual identity differences in DSM-5 alcohol and other drug use disorders and associations with alcohol and other drug misuse history among parents, offspring, and other relatives.

Background: The objectives of this study were to: (1) estimate the prevalence of family history of alcohol and other drug (AOD) misuse (positive family history [FH+]) in first- and second-degree relatives across sexual identity subgroups (i.e., lesbian, gay, bisexual, heterosexual); (2) compare AOD misuse among offspring of sexual minority and heterosexual parents; and (3) examine the relationships between FH+ and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alcohol use disorder (AUD) and other drug use disorder (ODUD) across sexual identity subgroups. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III (n = 36,309 non-institutionalized U.S. adults aged ≥ 18 years). Data collection occurred in households using structured diagnostic face-to-face interviews during 2012-2013. Results: The presence of FH+ in first- and second-degree relatives was most prevalent among bisexual women relative to all other sexual orientation subgroups. Multivariable regression analyses indicated that the odds of AUD and ODUD were higher among FH+ adults relative to negative family history (FH-) adults. Lesbian and bisexual women had higher odds of AUD compared to heterosexual women, controlling for any FH+; this sexual identity difference was not found for men. There were no significant differences in ODUD between heterosexual FH- men and gay FH- men. We found differences in AOD misuse among offspring of bisexual parents, but not gay or lesbian parents compared to heterosexual parents. Conclusions: Health professionals should consider the higher likelihood of a family history of AOD misuse among sexual minorities, especially bisexual women, when treating these individuals. The lack of differences in AOD misuse among offspring of gay or lesbian parents relative to heterosexual parents warrants attention for legal, policy, and clinical decisions.

Discrimination, Sexual Orientation Discrimination, and Severity of Tobacco Use Disorder in the United States: Results From the National Epidemiologic Survey on Alcohol and Related Conditions-III.

INTRODUCTION: Tobacco use is more prevalent among sexual minority populations relative to heterosexual populations. Discrimination is a known risk factor for tobacco use. However, the relationship between exposure to different forms of discrimination, such as racial or ethnic discrimination and sexual orientation discrimination, and tobacco use disorder (TUD) severity has not been examined. AIMS AND METHODS: Using data from the 2012-2013 National Epidemiologic Survey of Alcohol and Related Conditions-III (n = 36 309 US adults), we conducted multivariable logistic regression analyses to examine the associations among racial or ethnic discrimination, sexual orientation discrimination, and TUD severity for lesbian or gay-, bisexual-, and heterosexual-identified adults. Consistent with the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5), past-year moderate-to-severe TUD was defined as the presence of ≥4 DSM-5 TUD symptoms. RESULTS: Higher levels of lifetime racial or ethnic discrimination were associated with significantly greater odds of past-year moderate-to-severe TUD among sexual minorities (adjusted odds ratio [AOR] = 1.03, 95% confidence interval [CI] = 1.01-1.05) and heterosexuals (AOR = 1.04, 95% CI = 1.03-1.05). Stressful life events, mood disorder, and anxiety disorder had significant associations with moderate-to-severe TUD among sexual minorities (AOR range: 1.86-5.22, p < .005) and heterosexuals (AOR range: 1.71-3.53, p < .005). Among sexual minorities, higher levels of racial or ethnic and/or sexual orientation discrimination were associated with greater odds of any TUD (AOR = 1.02, 95% CI = 1.01-1.03). CONCLUSIONS: Sexual minorities and heterosexuals who experience higher levels of racial or ethnic discrimination are at heightened risk of having moderate-to-severe TUD. Exposure to higher levels of discrimination also increases the risk of having any TUD among sexual minority adults. Health providers and tobacco cessation professionals should be cognizant of the minority stressors experienced by their clients and their potential impact on TUD severity. IMPLICATIONS: This study is the first to show how experiences of racial or ethnic and sexual orientation discrimination are associated with DSM-5 TUD severity among sexual minority and heterosexual populations. Individuals exposed to multiple minority stressors may have increased vulnerability for developing TUD and related adverse health consequences. Our study underscores the importance of considering racial or ethnic discrimination and the multiple minority statuses that individuals may hold. Eliminating all forms of discrimination and developing interventions that are sensitive to the role that discrimination plays in TUD severity may attenuate the tobacco use disparities between sexual minority and heterosexual adults.

Sexual Orientation, Tobacco Use, and Tobacco Cessation Treatment-Seeking: Results From a National U.S. Survey.

Despite higher rates of tobacco use and smoking-related diseases among sexual minorities, tobacco cessation treatment-seeking behaviors (e.g., medication, nicotine replacement products) remain poorly understood across sexual orientation subgroups. This study examines tobacco cessation treatment-seeking behaviors associated with Diagnostic and Statistical Manual of Mental Disorders, 5th Edition tobacco use disorder (TUD) across the three major sexual orientation dimensions (identity, attraction, behavior) in U.S. adults. Prevalence estimates reflect data collected from a 2012-2013 national sample of adults 18 years and older. More than three-fourths of U.S. adults with TUD had never engaged in tobacco cessation treatment-seeking behaviors, regardless of sexual orientation. Despite having the highest rates of TUD, bisexual men and women had some of the lowest rates of tobacco cessation treatment-seeking. Men who identified as gay, reported same-sex attraction, or reported same-sex behaviors had the highest rates of tobacco cessation treatment-seeking. In contrast, women with same-sex attraction or same-sex behavior had higher rates of TUD but were less likely to engage in tobacco cessation treatment-seeking behaviors than women with only other-sex attraction or other-sex behavior, respectively. Heterosexual women were more likely to engage in tobacco cessation treatment-seeking than heterosexual men; this sex difference was not present for sexual minorities. Medications and nicotine replacement therapy products were the most prevalent forms of treatment-seeking. There were notable differences in tobacco cessation treatment-seeking behaviors based on sex and sexual orientation. Findings highlight the underutilization of tobacco cessation treatment-seeking among all U.S. adults and point to important factors to consider when working with sexual minorities who are trying to reduce or stop using tobacco.

A comprehensive assessment of predictors of fertility outcomes in men with non-obstructive azoospermia undergoing microdissection testicular sperm extraction.

BACKGROUND: Microdissection testicular sperm extraction (microTESE) in men with non-obstructive azoospermia (NOA) is the procedure that results in the highest number of sperm cells retrieved for in vitro fertilization (IVF). This study presents a novel assessment of predictors of sperm retrieval as well as downstream embryology and pregnancy outcomes in cases of men with NOA undergoing microTESE. METHODS: A retrospective chart review of 72 men who underwent microTESE for predictors of fertility outcomes including sperm retrieved at microTESE, embryology progression to embryo transfer (ET), clinical pregnancy, live birth, and surplus sperm retrieved for additional IVF/intracytoplasmic injection cycles beyond one initial cycle. Statistical models for each of these outcomes were fitted, with a p-value of < 0.05 considered significant for the parameters estimated in each model. RESULTS: Seventy-two men underwent microTESE, and 51/72 (70.8%) had sperm retrieved. Of those, 29/43 (67.4%) reached ET. Of the couples who underwent ET, 21/29 (72.4%) achieved pregnancy and 18/29 (62.1%) resulted in live birth. Of the men with sperm retrieved, 38/51 (74.5%) had surplus sperm cryopreserved beyond the initial IVF cycle. Age, testicular volume, FSH, and testicular histopathology were assessed as predictors for sperm retrieved at microTESE, progression to ET, pregnancy, live birth, and surplus sperm. There were no preoperative predictors of sperm retrieval, clinical pregnancy, or live birth. Age predicted reaching ET, with older men having increased odds. FSH level had a negative relationship with surplus sperm retrieved. Men with hypospermatogenesis histology had higher rates of sperm retrieval, clinical pregnancy, live birth, and having surplus sperm. CONCLUSIONS: Men who underwent microTESE with a hypospermatogenesis histopathology had better outcomes, including higher rates of sperm retrieval, clinical pregnancy, live birth, and having surplus sperm retrieved. Increasing male partner age increased the odds of reaching ET. No other clinical factors were predictive for the outcomes considered.

Factors associated with subchorionic hematoma formation in pregnancies achieved via assisted reproductive technologies.

PURPOSE: To determine if certain clinical and/or embryologic factors are independently associated with the increased prevalence of subchorionic hematoma (SCH) among pregnancies achieved via in vitro fertilization (IVF) with fresh embryo transfer (ET). DESIGN: Retrospective chart review. METHODS: In this retrospective study, data were abstracted from 210 autologous oocyte IVF clinical pregnancies that resulted from fresh ET at a single fertility center from January 2012 through December 2016. Clinical and embryology laboratory variables were analyzed as possible factors associated with the presence or absence of SCH in IVF pregnancies via bivariate associations and multivariable logistic regression analyses. Independent variables included prior uterine surgery versus no uterine surgery, peak estradiol, and progesterone levels, day 3 (n = 92) versus day 5 (n = 118) ET, and assisted hatching versus no assisted hatching. Among the day 5 ET subgroup of 118 patients, 117 had data for the variables inner cell mass (ICM) grading and trophectoderm (TE) because one day 5 ET was at the morula stage. RESULTS: We found a significant bivariate association between TE grading and SCH, where cases with TE grade "A" were significantly less likely to have SCH compared with cases with grades "B" or "C." This significant difference remained when adjusting for the other factors considered in a multivariable logistic regression model for the probability of SCH. CONCLUSIONS: The data analyzed here suggest that a less-advanced trophectoderm grade may be a potential factor that is associated with the presence of SCH in pregnancies achieved via IVF.

Attitudes About Consumer Strategies Among Americans in High-deductible Health Plans.

BACKGROUND: More than 70 million Americans are enrolled in a high-deductible health plan (HDHP), with high upfront cost-sharing to encourage strategies such as price shopping to mitigate out-of-pocket spending. Recent research suggests HDHP enrollees are reluctant to engage in these consumer strategies, but there is little information on why. OBJECTIVES: To describe associations between HDHP enrollees' attitudes about and intent to engage in consumer strategies. RESEARCH DESIGN: We conducted a nationally representative web survey of 1637 HDHP enrollees that included 2 hypothetical scenarios amenable to consumer strategies. For each scenario, we asked participants whether they would compare price or quality information, discuss cost with a provider, or try to negotiate a service price. We measured participants' ratings of the difficulty of each strategy, its effectiveness at reducing cost or increasing the likelihood of getting care, and how likely participants would be to actually engage in each strategy. RESULTS: Fewer than half of HDHP enrollees intended to engage in any of the surveyed strategies. Enrollees who viewed a consumer strategy as helpful were more likely to engage in that strategy; no associations were found with perceived difficulty of a strategy and intent to engage in it. CONCLUSIONS: HDHP enrollees may not pursue consumer strategies because they believe they are not helpful for getting care or lowering costs. Providers and payers should ensure these strategies are actually helpful to HDHP enrollees and that enrollees understand how they could use these strategies to reduce their out-of-pocket costs.

Serum Antimüllerian hormone does not predict elevated progesterone levels among women who undergo controlled ovarian hyperstimulation for in vitro fertilization.

Serum Antimüllerian hormone (AMH) has been shown to predict various in vitro fertilization (IVF) outcomes. AMH and progesterone (P) are products of granulosa cells of the ovary. Since overall granulosa cell number directly correlates with oocyte number and AMH production, the aim of this study is to evaluate whether or not serum AMH is associated with elevated P during controlled ovarian hyperstimulation (COH) for IVF. For this retrospective study, data were abstracted from charts of first IVF cycles of women (n = 201) who had undergone COH between May 2014 and May 2017. Groups were as follows: (A) AMH < 1 ng/mL (n = 32), (B) AMH 1-3.99 ng/mL (n = 109), (C), AMH ≥ 4 ng/mL (n = 60). The primary outcome measure was serum P level at trigger prior to oocyte retrieval. Mean serum P levels among groups A, B, and C were 0.92 ng/mL, 0.96 ng/mL, and 0.84 ng/mL, respectively. One-way ANOVA showed that there was no difference in mean serum P level among groups A, B, and C (p-value = 0.28). Multivariable linear regression with P as the dependent variable showed that total gonadotropin dose and peak estradiol level on day of trigger each had a significant positive relationship with P, and clinical pregnancy had a significant negative relationship. Although AMH is a predictor of certain IVF outcomes, AMH is not a predictor of elevated serum P level at trigger among women who undergo COH for IVF.

DSM-5 Alcohol Use Disorder Severity as a Function of Sexual Orientation Discrimination: A National Study.

BACKGROUND: Sexual minorities are more likely than their heterosexual counterparts to develop alcohol use disorder (AUD), and understanding the underlying reasons for this heightened risk is a public health priority. This study examined relationships between sexual orientation discrimination and DSM-5 AUD severity. METHODS: The 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions III conducted in-person interviews with a nationally representative sample of U.S. adults (N = 36,309). Approximately 2.8% of the target population self-identified as lesbian, gay, or bisexual, 3.1% had at least 1 past-year same-sex sexual partner, and 8.3% reported same-sex sexual attraction. RESULTS: Adults who identified as lesbian, gay, bisexual, heterosexual with same-sex attraction and/or current same-sex sexual partners, and those not sure of their sexual identity, had higher rates of individual DSM-5 AUD criteria than heterosexual-identified adults with only opposite-sex attraction and sexual partners. Respondents who were bisexual or unsure of their sexual identity consistently had the highest probabilities of endorsing each of these AUD criteria relative to the other subgroups. Differences in AUD severity across sexual orientation subgroups were much larger among women than among men. Sexual minorities who experienced higher levels of sexual orientation discrimination had significantly higher levels of AUD severity than sexual minorities who experienced lower levels or no discrimination. In particular, greater levels of sexual orientation discrimination increased the odds of impaired control criteria and pharmacologic criteria. Associations between prior-to-past-year sexual orientation discrimination and AUD severity were not as robust as those involving past-year discrimination. CONCLUSIONS: Sexual minorities are at substantially greater risk of severe DSM-5 AUD, and this is particularly true among those who experience high levels of sexual orientation discrimination. Findings indicate that proximal experiences of discrimination are more salient than distal experiences. AUD treatment should address recent sexual orientation discrimination given that such experiences are associated with more severe AUD.

Sexual Orientation Discrimination and Tobacco Use Disparities in the United States.

INTRODUCTION: Differences in tobacco/nicotine use by sexual orientation are well documented. Development of interventions requires attention to the etiology of these differences. This study examined associations among sexual orientation discrimination, cigarette smoking, any tobacco/nicotine use, and DSM-5 tobacco use disorder (TUD) in the United States. METHODS: We used data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions based on in-person interviews with a nationally representative sample of noninstitutionalized US adults. Approximately 8.3% of the target population was estimated to have same-sex sexual attraction, 3.1% had at least one same-sex sexual partner in the past-year, and 2.8% self-identified as lesbian, gay, or bisexual. RESULTS: Sexual attraction, sexual behavior, and sexual identity were significantly associated with cigarette smoking, any tobacco/nicotine use, and DSM-5 TUD. Risk of all tobacco/nicotine outcomes was most pronounced for bisexual adults across all three sexual orientation dimensions. Approximately half of sexual minorities who identified as lesbian or gay and one-fourth of those who identified as bisexual reported past-year sexual orientation discrimination. Sexual minorities who experienced high levels of past-year sexual orientation discrimination had significantly greater probability of past-year cigarette smoking, any tobacco/nicotine use, and TUD relative to sexual minorities who experienced lower levels of sexual orientation discrimination or no discrimination. CONCLUSIONS: Sexual minorities, especially bisexual adults, are at heightened risk of cigarette smoking, any tobacco/nicotine use, and DSM-5 TUD across all three major sexual orientation dimensions. Tobacco prevention and cessation efforts should target bisexual adults and consider the role that sexual orientation discrimination plays in cigarette smoking and treatment of TUD. IMPLICATIONS: Differences in tobacco/nicotine use by sexual orientation are well documented, but little is known about differences across all three sexual orientation dimensions (attraction, behavior, and identity) or the origins of these differences. This study is the first to show that differences in tobacco/nicotine use across the three sexual orientation dimensions for respondents who were exclusively heterosexually-oriented were minimal, but varied more substantially among sexual minority women and men across the three sexual orientation dimensions. Sexual minorities who experienced high levels of past-year sexual orientation discrimination had significantly greater probability of cigarette smoking, any tobacco/nicotine use and DSM-5 tobacco use disorder.

Sources of Variance in the Accuracy of Interviewer Observations.

In face-to-face surveys, interviewer observations are a cost-effective source of paradata for nonresponse adjustment of survey estimates and responsive survey designs. Unfortunately, recent studies have suggested that the accuracy of these observations can vary substantially among interviewers, even after controlling for household-, area-, and interviewer-level characteristics, limiting their utility. No study has identified sources of this unexplained variance in observation accuracy. Motivated by theoretical expectations from the observer bias literature, this study analyzed more than 45,000 open-ended justifications provided by interviewers in the U.S. National Survey of Family Growth (NSFG) for their observations on two key features of all sampled NSFG households: presence of children and expected probability of household response. The study finds that variability among interviewers in the cues used to record these observations (evident from the open-ended justifications) explains much of the previously unexplained variance in observation accuracy.

Associations Between Early Onset of E-cigarette Use and Cigarette Smoking and Other Substance Use Among US Adolescents: A National Study.

Introduction: This study examines the associations between early onset of e-cigarette use and cigarette smoking and other substance use behaviors among US adolescents. Methods: Data were collected via self-administered questionnaires from a nationally representative sample of 2299 US high school seniors attending public and private high schools during the spring of their senior year in 2015 as part of the Monitoring the Future study. Results: A higher percentage of adolescents who began using e-cigarettes in ninth grade or earlier (early onset) were found to report current and lifetime cigarette smoking and other substance use relative to those individuals who never used e-cigarettes or those who began using e-cigarettes later in the 12th grade. Multivariate logistic regression analyses indicated that the adjusted odds of alcohol use, cigarette smoking, marijuana use, nonmedical prescription drug use, and other illicit drug use among early onset e-cigarette users were significantly greater than those for individuals never having used e-cigarettes (adjusted odds ratios [AORs] ranged 9.5-70.6, p < .001). While these associations were significant for both experimental and frequent e-cigarette users, the effects of early onset were stronger among frequent e-cigarette users. Similarly, the odds of these substance use behaviors (except alcohol) among early onset e-cigarette users were also significantly greater than the odds for later onset e-cigarette users (AORs ranged 2.8-4.1, p < .05). Conclusions: Early onset of e-cigarette use was significantly associated with increased odds of cigarette smoking and other substance use behaviors. E-cigarette use is often preceded by alcohol use, cigarette smoking, and marijuana use, suggesting that more long-term prospective studies are warranted. Implications: To date, no studies have examined the probability of cigarette smoking and other substance use behaviors as a function of age at onset of e-cigarette use. In the present study, early onset of e-cigarette use was significantly associated with increased odds of cigarette smoking and other substance use behaviors. The findings reinforce the importance of addressing a wide range of substances including alcohol, traditional cigarettes, and marijuana when developing early primary prevention efforts to reduce e-cigarette use among youth.

Interviewer effects in food acquisition surveys.

OBJECTIVE: To understand the effects of interviewers on the responses they collect for measures of food security, income and selected survey quality measures (i.e. discrepancy between reported Supplemental Nutrition Assistance Program (SNAP) status and administrative data, length of time between initial and final interview, and missing income data) in the US Department of Agriculture's National Household Food Acquisition and Purchase Survey (FoodAPS). DESIGN: Using data from FoodAPS, multilevel models with random interviewer effects were fitted to estimate the variance in each outcome measure arising from effects of the interviewers. Covariates describing each household's socio-economic status, demographics and experience in taking the survey, and interviewer-level experience were included as fixed effects. The variance components in the outcomes due to interviewers were estimated. Outlier interviewers were profiled. SETTING: Non-institutionalized households in the continental USA (April 2012-January 2013). SUBJECTS: Individuals (n 14 317) in 4826 households who responded to FoodAPS. RESULTS: There was a substantial amount of variability in the distributions of the outcomes examined (i.e. time between initial and final interview, reported values for food security, individual income, missing income) among the FoodAPS interviewers, even after accounting for the fixed effects of the household- and interviewer-level covariates and removing extreme outlier interviewers. CONCLUSIONS: Interviewers may introduce error in food acquisition survey data when they are asked to interact with the respondents. Managers of future surveys with similarly complex data collection procedures could consider using multilevel models to adaptively identify and retrain interviewers who have extreme effects on data collection outcomes.

New options for national population surveys: The implications of internet and smartphone coverage.

Challenges to survey data collection have increased the costs of social research via face-to-face surveys so much that it may become extremely difficult for social scientists to continue using these methods. A key drawback to less expensive Internet-based alternatives is the threat of biased results from coverage errors in survey data. The rise of Internet-enabled smartphones presents an opportunity to re-examine the issue of Internet coverage for surveys and its implications for coverage bias. Two questions (on Internet access and smartphone ownership) were added to the National Survey of Family Growth (NSFG), a U.S. national probability survey of women and men age 15-44, using a continuous sample design. We examine 16 quarters (4 years) of data, from September 2012 to August 2016. Overall, we estimate that 82.9% of the target NSFG population has Internet access, and 81.6% has a smartphone. Combined, this means that about 90.7% of U.S. residents age 15-44 have Internet access, via either traditional devices or a smartphone. We find some evidence of compensatory coverage when looking at key race/ethnicity and age subgroups. For instance, while Black teens (15-18) have the lowest estimated rate of Internet access (81.9%) and the lowest rate of smartphone usage (72.6%), an estimated 88.0% of this subgroup has some form of Internet access. We also examine the socio-demographic correlates of Internet and smartphone coverage, separately and combined, as indicators of technology access in this population. In addition, we look at the effect of differential coverage on key estimates produced by the NSFG, related to fertility, family formation, and sexual activity. While this does not address nonresponse or measurement biases that may differ for alternative modes, our paper has implications for possible coverage biases that may arise when switching to a Web-based mode of data collection, either for follow-up surveys or to replace the main face-to-face data collection.
