Although the benefits of exercise are well documented, few published research studies have examined exercise in persons with schizophrenia. This pilot examined a 16-week walking program for outpatients diagnosed with schizophrenia (N = 10). Six-minute walking distance, body mass index, percent body fat and severity of psychiatric symptoms were measured. Experimental participants in the walking group experienced significant reductions in body fat (p = 0.03) compared to a control group not participating in the exercises during the same time period. Experimental participants also had greater aerobic fitness, lower body mass indexes, and fewer psychiatric symptoms than controls at the conclusion of the program. Research is needed to identify effective exercise interventions and feasible delivery modalities for persons with schizophrenia in community settings.

Interpersonal communication via the auditory modality is fundamental to normal human development. One of the prominent anatomical specializations supporting this communication is the transverse gyrus of Heschl on the superior surface of the temporal lobe. This gyrus frequently appears duplicated, either by a sulcus indenting the crown of an initially single gyrus (common stem), or by a complete posterior duplication. The frequency of these duplications has been reported to be elevated in populations with learning disabilities and genetic anomalies. The significance of this observation is unclear, however, due to conflicting reports of the base rate of duplication and the location of relevant sulcal landmarks. In this study we report the variation in frequency and location of the sulcal boundaries of Heschl's gyrus in volumetric magnetic resonance imaging scans of 105 normal controls aged 5-65. The major results were as follows: (i) duplications were unstable--the frequency of duplication ranged from 20 to 60% depending on distance from the midline; (ii) common stem duplications were more frequent than posterior duplications, particularly in the right hemisphere. Intra- and interindividual instability in sulcal landmarks pose serious obstacles to the attempt to map behavioral function onto the brain. Novel methods for dealing with structural variation are needed to facilitate the development of valid mapping techniques.

As part of a broad health survey, a random sample of 2,115 black and white adults, aged 18–96, were interviewed on weight and weight concerns. Significant age, gender, race, and social class differences were found. Forty‐six percent of black women, 28% of black men, 18% of white women, and 16% of white men were overweight. Prevalence of obesity was lowest among the youngest and oldest respondents. Three‐fourths of respondents at least 20 lb overweight considered themselves too heavy, as did one‐fourth of respondents who were not overweight. White women who reported “no weight problem” had a mean weight well below the lower limit of the normal weight range, whereas white men, black men and black women reporting “no weight problem” has mean weights above the normal weight range. Culture acceptance of overweight is discussed.
