The oral health of a group of 15-17 year old British school children of different ethnic origin.

The influence of ethnic origin on the oral health of a group of 472 British schoolchildren aged 15-17 years attending two adjacent schools was investigated. Ethnic origin was assessed as European (E; n = 197), Afro-Caribbean (AC; n = 97) and Asian (As; n = 140) leaving 38 subjects of other or mixed origin. Plaque, bleeding on probing and subgingival retentive factors, together with probing depths and attachment loss were recorded at the four approximal sites of teeth 16, 11, 26, 36, 31, 46. DMFT scores were collected for the whole mouth. Socio-economic status was assessed using a Classification of Residential Neighbourhoods (ACORN). Multiple regression analysis indicated that ethnic origin had a significant influence on plaque, subgingival calculus, gingivitis, pockets and DMFT scores. The overall prevalence of periodontitis was 11.2 per cent; European, Afro-Caribbean and Asian groups had prevalences of 3, 21 and 14 per cent respectively.

Pulmonary function: relation to aging, cigarette habit, and mortality.

The relation of pulmonary function to aging and cigarette habits has been examined cross sectionally and longitudinally in the Framingham cohort. On cross-sectional analysis, women were found to have lower forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV-1) values than men even after adjusting for height. Their FEV-1 percent was, on the other hand, higher than those of men. As the population aged over 10 years, their FVC and FEV-1 declined 9% to 27% depending upon age and sex. The FEV-1 percent, however, showed a decline only in the older age groups. In a cross-sectional analysis, cigarette smoking showed an inverse association to FVC and FEV-1 percent. Longitudinally, cigarette smokers showed a more rapid decline in FVC in 10 years than nonsmokers. On giving up smoking their FVC became more like that of the nonsmokers. A striking relation of FVC to mortality was noted in both sexes, which is not accounted for by associated cigarette habits.
