Self medication behaviors of illegal immigrants living along the U.S.-Mexico border

Mexican immigrants make up the largest subgroup of Hispanics living in the United States. The largest percentage of illegal immigrants comes from México. As such they are a subpopulation with limited access to health care and social services; their health seeking behaviors including self-medication behaviors that, aside from the intake of antibiotics, have not been studied in depth. The analysis of the data presented sought to document the medication behaviors of illegal immigrants living in El Paso County along the U.S.-México border. Of the 80 participants, 31 were taking medication on a regular basis. Of these, 28 claimed that at least one of the medications had been prescribed by a physician, 13 people had bought at least one of their medications in México, nine participants claimed that they had not paid for at least one of the medications they were taking, ten participants reported that they had skipped the doses of at least one of their medications due to monetary constraints. Participants were also asked if they had purchased medication in México during the year prior to the study, 68 of the 80 (85%) participants had bought 295 pharmaceutical products across the border themselves or through a third party. The most frequently purchased medications were antibiotics (17%), followed by syrups, pomades, creams, eardrops, and cold medicine as a group (15%), followed by analgesics (13%) and other non steroidal anti-inflammatory drugs (12%) and oral hypoglycemic agents (6%). ^

A comparison of healthcare access, healthcare utilization and asthma self-management for Hispanic children in border and non-border regions of Texas

The purpose of this culminating experience was to investigate the relationships between healthcare utilization, insurance coverage, and socioeconomic characteristics of children with asthma along the Texas-Mexico Border. A secondary data analysis was conducted on cross-sectional data from the Texas Child Asthma Call-back Survey, a follow-up survey to the random digit dialed Behavior Risk Factor Surveillance Study (BRFSS) conducted between 2006-2009 ( n = 556 adults living in households with a child with asthma).^ The proportion of Hispanic children with asthma in Border areas of Texas was more than twice that of non-Border areas (84.8% vs. 28.8%). Parents in Border areas were less likely to have their own health insurance (OR = 0.251, 95% C.I. = 0.117-0.540) and less likely to complete the survey in English than Spanish (OR = 0.251 95% C.I. = 0.117-0.540) than parents in non-Border areas. No significant socio-economic or health care utilization differences were noted between Hispanic children living in Border areas compared to Hispanic children living in non-Border areas. Children with asthma along the Texas-Mexico Border, regardless of ethnicity and language, have insurance coverage rates, reported cost barriers to care, symptom management, and medication usage patterns similar to those in non-Border areas. When compared to English-speakers, Spanish-speaking parents in Texas as a whole are far less likely to be taught what to do during an asthma attack (50.2% vs. 78.6%).^ Language preference, rather than ethnicity or geographical residence, played a larger role on childhood asthma-related health disparities for children in Texas. Spanish-speaking parents in are less likely to receive adequate asthma self-management education. Investigating the effects of Hispanic acculturation rates and incongruent parent-child health insurance coverage may provide better insight into the health disparities of children along the Texas-Mexico Border.^

Relationships among epilepsy self-management, health outcomes, and socioeconomic status

The purpose of this study was to investigate the association between epilepsy self-management and disease control and socio-economic status. Study participants were adult patients at two epilepsy specialty clinics in Houston, Texas that serve demographically and socioeconomically diverse populations. Self-management behaviors- medication, information, safety, seizure, and lifestyle management were tested against emergency room visits, hospitalizations, and seizure occurrence. Overall self-management score was associated with a greater likelihood of hospitalizations over a prior twelve month time frame, but not for three months, and was not associated with seizure occurrence or emergency room visits, at all. Scores on specific self-management behaviors varied in their relationships to the different disease control indicators, over time. Contrary to expectations based on the findings of previous research, higher information management scores were associated with greater likelihood of emergency room visits and hospitalizations, over the study's twelve months. Higher lifestyle management scores were associated with lower likelihood of any emergency room visits, over the preceding twelve months and emergency room visits for the last three months. The positive associations between overall self-management scores and information management behaviors and disease control are contrary to published research. These findings may indicate that those with worse disease control in a prior period employ stronger self-management efforts to better control their epilepsy. Further research is needed to investigate this hypothesis.^

Predictors of benzodiazepine self -administration behavior in anxious patients

The purpose of this study was to examine factors that may be associated with benzodiazepine (BZ) self-administration and risks of dependence in anxious patients. Preliminary work included examination of psychosocial characteristics and subjective drug response as potential predictors of medication use. Fifty-five M, F patients with generalized anxiety or panic disorder participated in a 3-week outpatient Choice Procedure in which they self-medicated “as needed” with alprazolam (Alz) and placebo. Findings showed that a large amount of variance in alprazolam preference, frequency, and quantity of use could be predicted by measures of anxiety, drug liking, and certain personality characteristics. The primary study extended this work by examining whether individual differences in Alz sensitivity also predict patterns of use. Twenty anxious patients participated in the study, which required 11 weekly clinic visits. Ten of these also participated in a baseline assessment of HPA-axis function that involved 24-hour monitoring of cortisol and ACTH levels and a CRH Stimulation Test. This assessment was conducted on the basis of prior evidence that steroid metabolites exert neuromodulatory effects on the GABA A receptor and that HPA-axis function may be related to BZ sensitivity and long-term disability in anxious patients. Patients were classified as either HIGH or LOW users based on their p.r.n. patterns of Alz use during the first 3 weeks of the study. They then participated in a 4-week dose response trial in which they received prescribed doses of medication (placebo, 0.25, 0.5, and 1.0mg Alz), each taken TID for 1 week. The dose response trial was followed by a second 3-week Choice Procedure. Findings were not indicative of biological differences in Alz sensitivity between the HIGH and LOW users. However, the HIGH users had higher baseline anxiety and greater anxiolytic response to Alz than the LOW users. Anxiolytic benefits of p.r.n. and prescribed dosing were shown to be comparable, and patients' conservative patterns of p.r.n. medication use were not affected by the period of prescribed dosing. Although there was not strong evidence to suggest relationships between HPA-axis function and Alz use or sensitivity, interesting findings emerged about the relationship between HPA-axis function and anxiety. ^
