Social functioning and facial expression recognition in survivors of pediatric brain tumors.

OBJECTIVE: To assess social functioning and facial expression recognition skill in survivors of pediatric brain tumors (BT) as compared to children with juvenile rheumatoid arthritis (JRA). METHODS: The social functioning of 51 survivors of BT and 31 children with JRA was assessed using a facial expression recognition task, questionnaire ratings of social functioning, and an IQ screener. RESULTS: After controlling for estimated IQ, survivors of BT made significantly more errors interpreting adult facial expressions as compared to children with JRA. Additionally, history of therapy and diagnosis age predicted performance on the child portion of the facial recognition task. Finally, survivors of BT demonstrated significantly impaired social functioning across multiple measures when compared to children with JRA. CONCLUSIONS: Survivors of pediatric BT showed significant deficits in social functioning as compared to an illness comparison group. Errors in facial expression recognition represent another method for evaluating deficits that contribute to social outcomes.

Unemployment, job retention, and productivity loss among employees with depression.

OBJECTIVE: This study comprehensively assessed the work outcomes of employees with depression. METHODS: We collected baseline and six-month follow-up survey data from 229 employees with depression and two employee comparison groups: a group of healthy patients for the control group (N=173) and a group with rheumatoid arthritis (N=87), a frequent source of work disability. Outcomes included new unemployment and, within the employed subgroup, job retention (versus job turnover), presenteeism (that is, diminished on-the-job performance and productivity), and absenteeism. RESULTS: At the six-month follow-up, persons with depression had more new unemployment--14 percent for persons in the dysthymia group, 12 percent for persons in the major depression group, and 15 percent for persons in the group with both dysthymia and major depression, compared with 2 percent for persons in the control group and 3 percent for persons in the rheumatoid arthritis group. Among participants who were still employed, those with depression had significantly more job turnover, presenteeism, and absenteeism. CONCLUSIONS: In addition to helping employees with depression obtain high-quality depression treatment, new interventions may be needed to help them to overcome the substantial job upheaval that this population experiences.

The work impact of dysthymia in a primary care population.

Physicians regard individuals with dysthymia as having relatively normal levels of functioning. This study examines in detail the work impact of dysthymia in a population of employed primary care patients. As part of an observational study conducted between 2001 and 2003 in clinics associated with three health plans in Massachusetts, we compared 69 patients diagnosed with DSM-IV dysthymia without concurrent major depressive disorder to 175 depression-free controls. Patients were employed at least 15 h per week, had no immediate plans to leave the labor market, and no major comorbid medical conditions. We assessed work absences and productivity loss due to on-the-job performance limitations ("presenteeism"). Patients with dysthymia, compared with controls, had less stable work histories and a greater frequency of significant problems at work. While absence rates were not significantly different (1.2 vs. 0.74 days, P<.09), individuals with dysthymia experienced significantly greater on-the-job productivity loss (6.3% vs. 2.8%, P<.0001). Dysthymia is an unrecognized cause of work impairment that has long-term negative consequences for individuals and their employers. The persistence of dysthymia with its serious impact on work functioning calls out for the development of new interventions.

The clinical and occupational correlates of work productivity loss among employed patients with depression.

Employers who are developing strategies to reduce health-related productivity loss may benefit from aiming their interventions at the employees who need them most. We determined whether depression's negative productivity impact varied with the type of work employees performed. Subjects (246 with depression and 143 controls) answered the Work Limitations Questionnaire and additional work questions. Occupational requirements were measured objectively. In multiple regression analyses, productivity was most influenced by depression severity (P < 0.01 in 5/5 models). However, certain occupations also significantly increased employee vulnerability to productivity loss. Losses increased when employees had occupations requiring proficiency in decision-making and communication and/or frequent customer contact (P < 0.05 in 3/5 models). The Work Limitations Questionnaire can help employers to reduce productivity loss by identifying health and productivity improvement priorities.

Does early physical activity predict body fat change throughout childhood?

BACKGROUND: Declining levels of physical activity in the population at large may be responsible in part for the rising rates of childhood obesity. Studies to date, however, have not consistently demonstrated such a protective effect. We used longitudinal data from the Framingham Children's Study (FCS) to address this important question. METHODS: We used 8 years of activity monitoring (Caltrac electronic motion sensors) and repeated anthropometry measures for 103 children to examine the effect of activity on body fat change from preschool to early adolescence. Longitudinal data analysis methods were employed to account for the use of repeated measures on these children. RESULTS: Children in the highest tertile of average daily activity from ages 4 to 11 years had consistently smaller gains in BMI, triceps, and sum of five skinfolds throughout childhood. By early adolescence (age 11), the sum of five skinfolds was 95.1, 94.5, and 74.1 for the low, middle, and high tertiles of activity, respectively (P for trend = 0.045). This protective effect of activity was evident for both girls and boys. CONCLUSION: This longitudinal study adds strong support for the hypothesis that higher levels of physical activity during childhood lead to the acquisition of less body fat by the time of early adolescence.

Alcohol consumption and risk of lung cancer: the Framingham Study.

BACKGROUND: Reports on the association between alcohol consumption and the risk of lung cancer have been inconsistent. The purpose of this study was to assess this association in a cohort study. METHODS: This study included 4265 participants in the original population-based Framingham Study cohort and 4973 subjects in the offspring cohort. Alcohol consumption data were collected periodically for both cohorts. We used the risk sets method to match control subjects to each case patient based on age, sex, smoking variables, and year of birth. We used a conditional logistic regression model to estimate the relative risk of lung cancer according to alcohol consumption. RESULTS: Alcohol consumption was generally light to moderate (i.e., <12 g/day) in both cohorts. During mean follow-ups of 32.8 years in the original and 16.2 years in the offspring cohorts, 269 cases of lung cancer occurred. In categories of total alcohol consumption of 0, 0.1-12, 12.1-24, and greater than 24 g/day, the crude incidence rates of lung cancer were 7.4, 13.6, 16.4, and 25.2 cases per 10 000 person-years, respectively, in the original cohort and 6.6, 4.3, 7.9, and 12.3 cases per 10 000 person-years, respectively, in the offspring cohort. However, after adjustment for age, sex, pack-years of smoking, smoking status, and year of birth in a multivariable conditional logistic regression model, relative risks for lung cancer from the lowest to the highest category of alcohol consumption were 1.0 (referent), 1.0 (95% confidence interval [CI] = 0.5 to 2.1), 1.0 (95% CI = 0.5 to 2.3), and 1.1 (95% CI = 0.5 to 2.3), respectively, in the original cohort and 1.0, 1.4 (95% CI = 0.5 to 3.6), 1.1 (95% CI = 0.3 to 3.6), and 2.0 (95% CI = 0.7 to 5.7), respectively, in the offspring cohort. CONCLUSION: Alcohol consumption among subjects in the Framingham Study, most of whom were light to moderate drinkers, was not statistically significantly associated with the risk of lung cancer.
