Searching for the 'Trigger': An ethnographic analysis of parental beliefs regarding autism causation and vaccination in Puerto Rico.

This study examines the personal beliefs held by parents of autistic children in Puerto Rico regarding the cause of their child's autism and how these beliefs may influence parental vaccination decision-making. This study seeks to contribute towards diversifying the autism literature by focusing on an autism community living in a relatively lower income, resource-deficit context. These findings expand our understandings of how parents of autistic children may perceive vaccines and how these perceptions are informed by various sources of knowledge. This ethnographic research study was conducted between May 2017 and August 2019. Methods included 350+ hours of participant-observation and semi-structured interviewing of 35 Puerto Rican parents of autistic children. 32 of these 35 parents interviewed believed autism to be the result of genetic risks that are 'triggered' by an unknown environmental factor. Suggested 'triggers' included various environmental contaminants and vaccinations. The subject of vaccination came up in every interview; 18 interviewed parents did not believe vaccines 'triggered' autism, 3 parents attributed their child's autism entirely to vaccines, while 14 considered vaccines to be one of several possible 'triggers'. It is important to note that no parents interviewed perceived vaccinations to be inherently or universally harmful. Rather, they perceived vaccinations to be one of many possible 'triggers' for a child predisposed to develop autism. In some cases, this perception prompted parents to oppose mandatory vaccination policies on the island. Parents shared nuanced, complex understandings of autism causation that may carry implications for COVID-19 vaccine uptake within the Puerto Rican autistic community.

Risk of opportunistic infection in the HAART era among HIV-infected Latinos born in the United States compared to Latinos born in Mexico and Central America.

There are few studies that compare opportunistic infection (OI) rates for U.S.-born, Mexican-born, and Central American-born Latinos in the pre- or post-highly active antiretroviral therapy (HAART) era. Data on 803 Latino persons in treatment for HIV infection in Los Angeles, California, were examined to evaluate differences in risk for specific and total OIs by country of origin. In a Cox proportional hazards regression analysis that controlled for HAART use, CD4 counts, and age, U.S.-born Latino women were more likely than Central American-born Latino women to develop an OI from 1996 to 2000 (hazard ratio [HR] = 2.9, 95% confidence intervals [CIs]: 1.3, 6.5). In a Poisson regression analysis, U.S.-born Latino men and women combined were at greater risk for HIV encephalopathy (RR = 3.4, 95% CIs: 1.2, 10.0) and Kaposi's sarcoma (RR = 2.9, 95% CIs: 1.1, 7.6). In addition to underreporting that may result from the use of English-based criteria for diagnosing HIV encephalopathy among Spanish-speaking patients, these HAART era data suggest that variation in OI risk among Latinos may also be explained by acculturation factors, such as loss of social support systems and negative lifestyle changes.
