Regular Physician Access and Obesity Status Among Underserved Asian and Pacific Islander American Immigrants in Los Angeles.

According to prior research, Asian and Pacific Islander American (APIA) immigrants often refrain from seeking health care unless necessitated by medical conditions. Utilizing data from health screenings conducted in APIA immigrant enclaves in Los Angeles, we hypothesize that poorer obesity status would predict higher rates of regular physician access. Analyses involved objectively measured percent body fat (%BF) and survey responses collected between 2011 and 2019. We assessed the association between obesity status and regular physician access, adjusting for insurance status, demographic, and socioeconomic factors. The study population (n = 4102) primarily consisted low-income, low English proficiency APIAs. Participants with a regular physician were significantly more likely to be obese compared to participants without (adjusted odds ratio [aOR] = 1.28, 95% confidence interval [CI] = [1.03, 1.58], P = .02). This association may suggest that care was sought reactively rather than proactively within this community. Interventions with emphasis on cultural competency and language services may encourage preventative care utilization among this understudied community.

Hepatitis B Screening and Awareness in the Milwaukee Hmong Community.

INTRODUCTION: Hepatitis B virus (HBV) infection disproportionately affects the Hmong ethnic group, with reported US prevalence rates up to 20%, but data for Wisconsin's large Hmong community is lacking. We assessed the prevalence of HBV at Hmong screening events and whether small-group counseling affects HBV knowledge. METHODS: Free HBV screening events were held in Milwaukee, Wisconsin at a Hmong market, a local church, and annual Hmong New Year festival. Eligible Hmong subjects age 18 years and older also were invited to complete a 15-point survey on HBV knowledge at baseline and after education sessions. Hmong interpreters were available, and free HBV screening was offered. RESULTS: A total of 187 participants were tested for HBV, and 161 completed surveys. After education sessions, the mean knowledge score rose to 10.6 (71%) vs the pre-education score of 6.7 (45%) (P <0.0001). Active HBV [HBsAg(+) HBsAb(-)] was diagnosed in 18 participants (9.6%), 53 (28.3%) were susceptible [HBsAg(-) and HBsAb(-)], 5 (3.4%) were in the gray zone [HBsAg(-) with low/inadequate HBsAb(+) titer], and the remaining 110 (58.8%) were immune [HBsAg(-)/HBsAb(+)]. Of the 18 individuals with active HBV, 13 were male and 5 were female [age range 24-66]. CONCLUSION: Despite evidence that small-group education with visual aids is effective in enhancing HBV knowledge in the Hmong population, a significant knowledge gap remained on post-education scores, suggesting that better tools or repeated interventions may be warranted. While we acknowledge that this convenience sampling may have introduced biases, the rate of active HBV infection in Wisconsin is much higher than general US population reports, and a quarter of those tested were found to be susceptible to HBV.

Testicular growth and regression are not correlated with Dio2 expression in a wild male songbird, sturnus vulgaris, exposed to natural changes in photoperiod.

Timing of seasonal breeding in birds and mammals is regulated by changing the day length and is dependent on the presence of thyroid hormones. A mechanism for thyroid-dependent control of seasonality has been proposed, in which exposure to long day lengths induces rapid local conversion of T4 to its bioactive form, T3, via the up-regulation of the enzyme type 2 iodothyronine deiodinase (Dio2) in the brain, and the down-regulation of Dio3 (which inactivates T3). Such changes were correlated with gonadotropin release and gonadal growth in quail. This mechanism was elucidated in a domesticated species (quail) exposed to unnatural acute changes in day length. Here we investigated the Dio2/Dio3 mechanism in a wild species, the European starling, under naturally changing day length. Although Dio2 expression varied seasonally, Dio3 did not. We found no correlation of Dio2 with photoperiod, seasonal regulation of GnRH, or testicular volume. The observed differences in data from starlings and quail could be a result of phylogeny, genetic drift from founder populations, or differences in reproductive seasonality in addition to or instead of arising from domestication or use of artificially changing photoperiods. Overall, the data indicate that in a wild species exposed to natural changes in day length, the current proposed mechanism for photoperiodic timing is less straightforward than is generally accepted and might not be as universally applicable as previously thought.
