Youth perspectives on sexual fluidity
Sexual fluidity has been defined as change over time in one or more dimensions of sexual orientation (identity, attractions, gender of sexual partners). As research on sexual fluidity among young people expands, it is critical to understand how adolescents and young adults understand sexual fluidity. Qualitative data were analysed from the USA-based Sexual Orientation Fluidity in Youth Study, which recruited 3,550 participants aged 14–25 years fr…
One in ten adolescents and young adults report changes in their sexual orientation identity over 2-month follow-up: Results from a longitudinal cohort study
Understanding the frequency and patterns of experiencing changes in sexual orientation identity (SOI) is critical to the health of adolescents and young adults (AYA). Failure to measure and acknowledge change experiences may miss opportunities to tailor care, such as sexual and reproductive health care, accordingly. Much of the prior research among AYA assesses change either retrospectively, or prospectively over relatively long time intervals. T…

Fluidity in Gender Identity and Sexual Orientation Identity in Transgender and Nonbinary Youth
Changes in sexual orientation identity (SOI) and gender identity (GI) have rarely been studied in transgender and/or nonbinary youth (TNBY), but documenting such changes is important for understanding identity development and gender transition and supporting the needs of TNBY. This study examined the frequency and patterning of changes in GI and SOI across 3 months (T1-T2) and 1.5 years (T1-T4) among 183 TNBY (baseline age 14-17 years; 83.6% Whit…

The Impact of Influencers on Cigar Promotions: A Content Analysis of Large Cigar and Swisher Sweets Videos on TikTok
Little is known about the content, promotions, and individuals in cigar-related videos on TikTok. TikTok videos with large cigar and Swisher Sweets-related hashtags between July 2016 and September 2020 were analyzed. Follower count was used to identify influencers. We compared content characteristics and demographics of featured individuals between cigar types, and by influencer status. We also examined the association between content characteris…
Associations between sociodemographic factors and receiving "ask and advise" services from healthcare providers in India: Analysis of the national Gats-2 dataset
This study offers a helpful starting point in identifying opportunities to address a critical service delivery gap in India. Given the existing burden on the public health and health systems, scale-up will require innovative, resource-appropriate solutions. The findings also point to the need to center equity in the design and scale-up of tobacco cessation supports so that marginalized and underserved groups will have equitable access to these cr…

OBJECTIVE: This study examined the effect of integrated care on physical and mental health outcomes among low-income Latino participants on the US-Mex…
The Impact of State Firearm Laws on Homicide Rates in Suburban and Rural Areas Compared to Large Cities in the United States, 1991‐2016
PURPOSE: This article aims to examine whether state firearm laws impact homicide rates differently in suburban and rural areas compared to large cities in the United States. METHODS: We analyzed serial, cross-sectional data for the 26-year period 1991-2016 using a panel design. We examined the relationship between 6 specific state firearm laws and homicide rates in large cities (those with greater than 100,000 people in 1990) and in all geographi…
The influence of a ban on outpatient intravenous antibiotic therapy among the secondary and tertiary hospitals in China
Future efforts may include 1) to de-escalate both oral and IV antibiotic therapy in paediatric and reduce oral antibiotic therapy among adults in outpatient clinics, 2) to reduce unnecessary referrals by OD doctors to ED, primary care, or inpatient services and better coordinate for patients who clinically need IV antibiotics, 3) to incorporate demand-side tailored measures, such as public education campaigns, and 4) to improve doctor-patient com…

Easiness of Legal Access to Concealed Firearm Permits and Homicide Rates in the United States
Objectives. To examine the relation of “shall-issue” laws, in which permits must be issued if requisite criteria are met; “may-issue” laws, which give law enforcement officials wide discretion over whether to issue concealed firearm carry permits or not; and homicide rates.

Effects of Prenatal Poverty on Infant Health: State Earned Income Tax Credits and Birth Weight
This study estimates the effects of prenatal poverty on birth weight using changes in state Earned Income Tax Credits (EITC) as a natural experiment. We seek to answer two questions about poverty and child wellbeing. First, are there associations between prenatal poverty and lower birth weights even after factoring out unmeasured potential confounders? Because birth weight predicts a range of outcomes across the life course, lower birth weights t…

The Alcohol Policy Environment and Policy Subgroups as Predictors of Binge Drinking Measures Among US Adults
Objectives. We examined the relationships of the state-level alcohol policy environment and policy subgroups with individual-level binge drinking measures. Methods. We used generalized estimating equations regression models to relate the alcohol policy environment based on data from 29 policies in US states from 2004 to 2009 to 3 binge drinking measures in adults from the 2005 to 2010 Behavioral Risk Factor Surveillance System surveys. Results. A…

An Empirical Evaluation of the US Beer Institute’s Self-Regulation Code Governing the Content of Beer Advertising
Objectives. We evaluated advertising code violations using the US Beer Institute guidelines for responsible advertising. Methods.

Fifteen public health professionals completed ratings using quantitative scales measuring the content of alcohol advertise…
Changes in the self‐regulation guidelines of the US Beer Code reduce the number of content violations reported in TV advertisements
From a public health perspective, alcohol advertising should not be directed at vulnerable groups, nor should it portray excessive drinking or other objectionable content such as illegal activity. To promote the responsible advertising of alcoholic beverages, alcohol industry groups have developed self‐regulation guidelines that describe which types of content (and exposure markets) are unacceptable. In 2006 the US Beer Institute revised the cont…

Gender norms and economic empowerment intervention to reduce intimate partner violence against women in rural Côte d’Ivoire: A randomized controlled pilot study
BACKGROUND: Gender-based violence against women, including intimate partner violence (IPV), is a pervasive health and human rights concern. However, relatively little intervention research has been conducted on how to reduce IPV in settings impacted by conflict. The current study reports on the evaluation of the incremental impact of adding "gender dialogue groups" to an economic empowerment group savings program on levels of IPV. This study took…
Patient Navigation to Promote Smoking Cessation among Low-Income Primary Care Patients: A Pilot Randomized Controlled Trial
We conducted a pilot randomized controlled trial to determine the feasibility and acceptability of a patient navigation intervention. Forty-seven smokers from one safety-net hospital were randomized to either a control group, in which they received a smoking cessation brochure and a list of smoking cessation resources, or a navigation group, in which they received the smoking cessation brochure, a list of smoking cessation resources, and patient …

Overdose rescues by trained and untrained participants and change in opioid use among substance-using participants in overdose education and naloxone distribution programs: A retrospective cohort stud…
Among 4926 substance users who participated in OEND, 373(7.6%) reported administering naloxone during an overdose rescue. We found few differences in behavior between trained and untrained overdose rescuers. Prospective studies will be needed to determine the optimal level of training and whether naloxone rescue kits can meet an over-the-counter standard. With no clear evidence of increased heroin use, this concern should not impede expansion of …
