Radon-contaminated drinking water from private wells: an environmental health assessment examining a rural Colorado mountain community's exposure.

In the study discussed in this article, 27 private drinking water wells located in a rural Colorado mountain community were sampled for radon contamination and compared against (a) the U.S. Environmental Protection Agency's (U.S. EPA's) proposed maximum contaminant level (MCL), (b) the U.S. EPA proposed alternate maximum contaminate level (AMCL), and (c) the average radon level measured in the local municipal drinking water system. The data from the authors' study found that 100% of the wells within the study population had radon levels in excess of the U.S. EPA MCL, 37% were in excess of the U.S. EPA AMCL, and 100% of wells had radon levels greater than that found in the local municipal drinking water system. Radon contamination in one well was found to be 715 times greater than the U.S. EPA MCL, 54 times greater than the U.S. EPA AMLC, and 36,983 times greater than that found in the local municipal drinking water system. According to the research data and the reviewed literature, the results indicate that this population has a unique and elevated contamination profile and suggest that radon-contaminated drinking water from private wells can present a significant public health concern.

Attending to social vulnerability when rationing pandemic resources.

Pandemic plans are increasingly attending to groups experiencing health disparities and other social vulnerabilities. Although some pandemic guidance is silent on the issue, guidance that attends to socially vulnerable groups ranges widely, some procedural (often calling for public engagement), and some substantive. Public engagement objectives vary from merely educational to seeking reflective input into the ethical commitments that should guide pandemic planning and response. Some plans that concern rationing during a severe pandemic recommend ways to protect socially vulnerable groups without prioritizing access to scarce resources based on social vulnerability per se. The Minnesota Pandemic Ethics Project (MPEP), a public engagement project on rationing scarce health resources during a severe influenza pandemic, agrees and recommends an integrated set of ways to attend to the needs of socially vulnerable people and avoid exacerbation of health disparities during a severe influenza pandemic. Among other things, MPEP recommends: 1. Engaging socially vulnerable populations to clarify unique needs and effective strategies; 2. Engaging socially vulnerable populations to elicit ethical values and perspectives on rationing; 3. Rejecting rationing based on race, socioeconomic class, citizenship, quality of life, length of life-extension and first-come, first-served; 4. Prioritizing those in the general population for access to resources based on combinations of risk (of death or severe complications from influenza, exposure to influenza, transmitting influenza to vulnerable groups) and the likelihood of responding well to the resource in question. 5. Protecting critical infrastructures on which vulnerable populations and the general public rely; 6. Identifying and removing access barriers during pandemic planning and response; and 7. Collecting and promptly analyzing data during the pandemic to identify groups at disproportionate risk of influenza-related mortality and serious morbidity and to optimize the distribution of resources.

Factors influencing physical activity behaviors in colorectal cancer survivors.

PURPOSE: To elucidate factors that impact intention (INT) to be active as well as actual physical activity (PA) behavior in colorectal cancer survivors (CRC-S) using the theory of planned behavior (TpB). Planning for PA was explored as a mediator of the INT-behavior relationship. Chemotherapy-induced neuropathy and fatigue were also explored. DESIGN: A cross-sectional quantitative mailed survey was used. SETTING: The study was conducted among community-dwelling adults living in Pennsylvania when diagnosed with colorectal cancer (CRC). SUBJECTS: Subjects comprised 843 CRC-S diagnosed with CRC in Pennsylvania in 2009. MEASURES: The survey included questions about planning for PA, TpB constructs, medical and social variables, and PA as measured by a modified Godin Leisure Time Questionnaire. ANALYSIS: Descriptive statistics were used to characterize the sample. A mediation analysis was used to determine if planning mediated the relationship between INT and actual PA behavior. A stepwise regression was used to determine predictors of INT and PA. RESULTS: Ninety-six CRC-S responded, with 25% meeting PA recommendations for health promotion, suggesting that CRC-S are insufficiently active. Perceived behavioral control (PBC) and social norm (SN) accounted for 43% of the variance in INT, whereas 30% of the variance in PA was explained by PBC and age. Neuropathy negatively impacted PA behavior (p = .008). Both action and coping planning partially mediated the INT-behavior relationship (ß = 20.08, p = .007; ß = 22.85, p = .001, respectively). CONCLUSION: Survivors at risk for inactivity are those with low PBC, low SN, and neuropathy, and those who are older.

Associations between adverse childhood experiences, psychological distress, and adult alcohol problems.

OBJECTIVE: To examine the mediating role of psychological distress on the relationship between adverse childhood experiences and adult alcohol problems by gender. METHODS: Linear and logistic regression analyses were conducted on 7279 Kaiser-Permanente members, aged >18 years. RESULTS: Psychological distress mediated significant proportions of alcohol problems associated with childhood emotional abuse and neglect, physical abuse and neglect, mental illness in the household, parental separation or divorce, sexual abuse, and household drug use among women and mental illness in the household, emotional neglect, physical abuse, household drug use, and sexual abuse among men. CONCLUSION: It may be important to identify early childhood trauma and adult psychological distress in programs that focus on reducing alcohol abuse.

The mediating sex-specific effect of psychological distress on the relationship between adverse childhood experiences and current smoking among adults.

BACKGROUND: Research suggests that ACEs have a long-term impact on the behavioral, emotional, and cognitive development of children. These disruptions can lead to adoption of unhealthy coping behaviors throughout the lifespan. The present study sought to examine psychological distress as a potential mediator of sex-specific associations between adverse childhood experiences (ACEs) and adult smoking. METHOD: Data from 7,210 Kaiser-Permanente members in San Diego California collected between April and October 1997 were used. RESULTS: Among women, psychological distress mediated a significant portion of the association between ACEs and smoking (21% for emotional abuse, 16% for physical abuse, 15% for physical neglect, 10% for parental separation or divorce). Among men, the associations between ACEs and smoking were not significant. CONCLUSIONS: These findings suggest that for women, current smoking cessation strategies may benefit from understanding the potential role of childhood trauma.
