RESUMO
Arthritis researchers have thoroughly documented a powerful relationship between years of education and health outcomes, but they have not documented the role of literacy. The authors examined the associations between literacy and arthritis health status measures. Participants were recruited from southeastern urban and rural areas. Rapid Estimate of Adult Literacy in Medicine, which provides an estimate of reading level in less than 3 minutes, was administered to 447 participants at baseline in 2 community-based randomized controlled trials of lifestyle interventions designed for aging sedentary adults with arthritis. Those who read below ninth grade were considered to have low literacy. Among the 447 study participants, the median sample age was 69 years. A majority of the participants were women (86%), Caucasian (80%), overweight or obese (72%). Of all participants, 20% had low literacy. Significantly more African Americans (54%) than Caucasians (12%) had low literacy levels (p < .001). Individuals with low literacy did not have significantly worse disability or arthritis symptoms than individuals with adequate literacy (all ps > .05). Among our study participants, 1 in 5 had low literacy, but literacy was not associated with health status in this population.

Sleeplessness, a universal condition with diverse causes, may be increasingly diagnosed and treated (or medicalized) as insomnia. We examined the trend in sleeplessness complaints, diagnoses, and prescriptions of sedative hypnotics in physician office visits from 1993 to 2007. Consistent with the medicalization hypothesis, sleeplessness complaints and insomnia diagnoses increased over time and were far outpaced by prescriptions for sedative hypnotics. Insomnia may be a public health concern, but potential overtreatment with marginally effective, expensive medications with nontrivial side effects raises definite population health concerns.

Given that more than one third of some cohorts of cancer survivors exhibit post-traumatic stress disorder (PTSD) symptomatology, this study examines how trauma outcomes might relate to quality of life (QOL). Eight hundred thirty survivors of adult lymphoma were assessed for PTSD, post-traumatic growth (PTG) and QOL. Structural equation modeling revealed that QOL was best explained by the model in which stressors (e.g., co-morbidities) were mediated by PTSD and PTG. Trauma outcomes mediated the relationship between specific stressors and QOL. These findings support using PTSD and PTG as a diagnostic framework in understanding symptomatology in survivors.

PURPOSE: Television (TV) use has been linked with poor eating behaviors and obesity in young people. This study examines the association between TV watching and paying attention to TV commercials with buying and requesting snacks seen on commercials, and eating snacks while watching TV among youth in China. METHODS: Data from 1,552 participants (ages 6-17.99) in the 2004 China Health and Nutrition Survey were analyzed cross-sectionally. The 2004 China Health and Nutrition Survey was conducted in nine Chinese provinces. RESULTS: Most respondents (92.2%) reported watching TV; on average children (6-11.99 years old) and adolescents (12-17.99 years old) watched TV for 9-10 hours per week. Nearly half (42.9%) of all the respondents said they "sometimes" or "often" paid attention to TV commercials. Respondents who reported paying attention to commercials had higher odds of requesting snacks (odds ratio [OR] = 3.43; 95% confidence interval [CI] = 2.55-4.60) and buying snacks (OR = 2.73; 95% CI = 2.17-3.43) seen on TV, and eating snacks while watching TV (OR = 1.60; 95% CI = 1.23-2.07) than those who did not pay attention. However, frequency of watching TV was not significantly related to snacking. CONCLUSION: Attention to TV commercials for snack foods may be one of the factors affecting the increase in obesity among children and adolescents in China.

OBJECTIVE: To examine the effect of outcome expectation for exercise (OEE), helplessness, and literacy on arthritis outcomes in 2 community-based lifestyle randomized controlled trials (RCTs) conducted in urban and rural communities with older adults with arthritis. METHODS: Data from 391 participants in 2 RCTs were combined to examine associations of 2 psychosocial variables: helplessness and OEE, and literacy with arthritis outcomes. Arthritis outcomes namely, the Health Assessment Questionnaire-Disability Index (HAQ-DI) and arthritis symptoms pain, fatigue and stiffness Visual Analogue Scales (VAS), were measured at baseline and at the end of the interventions. Complete baseline and post-intervention data were analyzed using STATA version 9. RESULTS: Disability after intervention was not predicted by helplessness, literacy, or OEE in the adjusted model. Arthritis symptoms after the intervention were all significantly predicted by helplessness at various magnitudes in adjusted models, but OEE and literacy were not significant predictors. CONCLUSION: When literacy, helplessness, and OEE were examined as predictors of arthritis outcomes in intervention trials, they did not predict disability. However, helplessness predicted symptoms of pain, fatigue, and stiffness, but literacy did not predict symptoms. PRACTICE IMPLICATIONS: Future sustainable interventions may include self-management components that address decreasing helplessness to improve arthritis outcomes.

This study describes and validates the Infant Feeding Style Questionnaire (IFSQ), a self-report instrument designed to measure feeding beliefs and behaviors among mothers of infants and young children. Categorical confirmatory factor analysis was used to estimate latent factors for five feeding styles, laissez-faire, restrictive, pressuring, responsive and indulgent, and to validate that items hypothesized a priori as measures of each style yielded well-fitting models. Models were tested and iteratively modified to determine the best fitting model for each of 13 feeding style sub-constructs, using a sample of 154 low-income African-American mothers of infants aged 3-20 months in North Carolina. With minor changes, models were confirmed in an independent sample of 150 African-American first-time mothers, yielding a final instrument with 39 questions on maternal beliefs, 24 questions on behaviors and an additional 20 behavioral items pertaining to solid feeding for infants over 6 months of age. Internal reliability measures for the sub-constructs ranged from 0.75 to 0.95. Several sub-constructs, responsive to satiety cues, pressuring with cereal, indulgent pampering and indulgent soothing, were inversely related to infant weight-for-length z-score, providing initial support for the validity of this instrument for assessing maternal feeding beliefs and behaviors that may influence infant weight outcomes.

OBJECTIVE: Although discriminatory health care experiences and health care provider distrust have been shown to be associated with health care disparities, little is known about their contribution to racial/ethnic disparities in antiretroviral therapy adherence. We therefore sought to assess the extent to which discriminatory health care experiences and health care provider distrust influence treatment-related attitudes, beliefs, and self-reported adherence in a national sample of HIV-infected patients. STUDY DESIGN: This secondary analysis used data from the HIV Cost and Services Utilization Study. We used structural equation modeling to identify pathways from minority status to adherence through discrimination, distrust, and treatment-related attitudes and beliefs. PARTICIPANTS: The sample was the 1886 participants who completed the baseline and 2 follow-up interviews and were prescribed antiretroviral therapy at the second follow-up interview (54% white, 28% black, 14% Hispanic, and 3% others). RESULTS: Minorities were less likely to report perfect adherence than whites (40% vs. 50%, P < or = 0.001). Over one third (40%) of all participants reporting ever having discriminatory health care experiences since having HIV, and 24% did not completely or almost completely trust their health care providers. The effect of minority status on adherence persisted in the full model. More discrimination predicted greater distrust, weaker treatment benefit beliefs, and, in turn, poorer adherence. Distrust affected adherence by increasing treatment-related psychological distress and weakening treatment benefit beliefs. CONCLUSIONS: The relationship between minority status and adherence was not fully explained by patient-level factors. Future studies should consider conceptualizing minority status as a contextual factor rather than predictor.

We report on a study of potential sources of therapeutic misconception in early phase gene transfer research, examining how investigators and their consent forms represent the prospect for direct benefit. Our analysis demonstrates that even though half of PIs said they expected direct medical benefit for their subjects, they did not necessarily convey this to their subjects. What they reported telling subjects resembled what was written in their consent form, which suggests that, far from being irrelevant, the consent form is an influential component of the consent process. We also demonstrate that the language used to describe direct benefit in consent forms and PIs' discussions was mostly vague, ambiguous, and indeterminate about benefit, rather than clearly negative. This was especially true for cancer and vascular disease trials. Our respondents found the problem of balancing hopes and expectations, for themselves and for their subjects, extraordinarily challenging. In the current era, investigators face such challenges without consistent normative guidance or agreed-upon standards for how to talk about scientific promise and uncertainty in early phase trials. This dilemma cannot be effectively addressed by individual investigators alone, but must be acknowledged and openly discussed by the scientific community at large.
