The prevalence of psychiatric morbidity appears to be lower in rural than urban areas. Using the Fourth National GP Morbidity Survey (1991-1992) we have compared patterns of GP consultation for mental illness by young people living in rural and urban areas to investigate whether patterns of morbidity are reflected in GP help-seeking. We investigated whether urban-rural differences were due to differences in the socio-economic characteristics of residents. The crude rate ratio for consultation for mental disorder in rural compared to urban males was 0.55 (95% Cl 0.47 to 0.65) and for females was 0.78 (0.71 to 0.86). After controlling for socioeconomic differences between rural and urban areas, consultation rates for mental illness were 30% (95% Cl 19% to 41%) lower in males and 16 per cent (8% to 24%) lower in females in rural compared to urban areas. These findings are in line with population surveys indicating that levels of mental illness are lower in rural compared to urban areas.

Further studies are needed to investigate possible area effects on the prevalence of mental illness. reflects differences in the socio-
