Few large epidemiological studies have examined the co-occurrence of autism and asthma. We performed a cross-sectional study to examine this association using the 2007 National Survey of Children's Health dataset (n = 77,951). We controlled for confounders and tested for autism-secondhand smoke interaction. Prevalence of asthma and autism were 14.5 % (n = 11,335) and 1.81 % (n = 1,412) respectively. Unadjusted odds ratio (OR) for asthma among autistic children was 1.35(95 % CI 1.18-1.55). Adjusting for covariates (age, gender, body mass index, race, brain injury, secondhand smoke and socio-economic status) attenuated the OR to 1.19 (95 % CI 1.03-1.36). Autism-secondhand smoke interaction was insignificant (p = 0.38). Asthma is approximately 35 % more common in autistic children; screening may be an efficient approach to reduce risk of morbidity due to asthma.

Objectives. We tested whether social integration protects against memory loss and other cognitive disorders in late life in a nationally representative US sample of elderly adults, whether effects were stronger among disadvantaged individuals, and whether earlier cognitive losses explained the association (reverse causation). Methods. Using data from the Health and Retirement Study (N=16638), we examined whether social integration predicted memory change over 6 years. Memory was measured by immediate and delayed recall of a 10-word list. Social integration was assessed by marital status, volunteer activity, and frequency of contact with children, parents, and neighbors. We examined growth-curve models for the whole sample and within subgroups. Results. The mean memory score declined from 11.0 in 1998 to 10.0 in 2004. Higher baseline social integration predicted slower memory decline in fully adjusted models (P Conclusions. Our study provides evidence that social integration delays memory loss among elderly Americans. Future research should focus on identifying the specific aspects of social integration most important for preserving memory.

One hundred and thirty-nine young adults viewed one of three episodes of a television program about a female action hero titled Xena: Warrior Princess. Programs varied in portrayals of Xena's shadow, the dark but also life-preserving facet of the personality. Participants of both genders who had higher levels of traditionally masculine personality characteristics were most likely to perceive Xena as a role model. Men were more likely than women to perceive Xena as a role model when she was portrayed with very little male shadow. Story themes describing women's heroic roles involved using your mind, not the sword, as well as the value of compassion during conflicts, themes that are in keeping with traditional feminine values. The results suggest that viewer acceptance of heroic qualities in women depends on viewer characteristics as well as program themes that include valued feminine qualities, implications for portrayals of heroic women characters are discussed.
