There is an association between race and tooth loss that is mainly explained by current and early life socioeconomic variables, but not by behavioural factors and self-reported discrimination.

O projeto que se apresenta surgiu do interesse e curiosidade de uma criança que ia ter um irmão. Foi realizado em contexto de estágio num Jardim de Infância de uma Instituição Particular de Solidariedade Social (IPSS) que se rege pelo modelo pedagógico do Movimento da Escola Moderna (MEM).

open revascularisation remained fairly constant. For men aged <60 years, the age-specific rate of amputations increased significantly (p¼0.003) from 21.1 to 61.1 per 100 000 over the study period (RR¼1.33, 95% CI 1.09 to 1.61). Therapeutic endovascular procedure rates increased significantly (p<0.001) for men aged 60 to 74 years (RR¼1.65; 95% CI 1.42 to 1.92) and 75 years or older (RR¼2.6; 95% CI 1.96 to 3.47). Equally, a significant increase (p<0.001) in the population rates of therapeutic endovascular procedures for women of all age groups occurred over the period examined. Conclusions A substantial change in the practice of vascular surgery has occurred in Scotland in the last 2 decades perhaps in response to new technologies and new clinical guidelines. This change should inspire further research to determine the outcomes of these vascular procedures Introduction Social inequalities in pregnancy outcomes have been extensively described, but studies that explain these inequalities comprehensively are lacking. This analysis evaluated the contribution of material, psychosocial, behavioural, nutritional, and obstetrical factors in explaining social inequalities in preterm delivery. Methods The data were based on a prospective cohort of 1109 Irish pregnant women. Preterm delivery was obtained from clinical hospital records. Socio-economic status was measured using educational level. The association between educational level and preterm delivery was examined using Cox model. Results Educational level was found to be a significant predictive factor of preterm delivery; women with low educational level were more likely to have a preterm delivery (HR¼2.14, 95% CI 1.04 to 4.38) after adjustment for age and parity. Rented and crowded home, smoking, alcohol consumption, and intake of saturated fatty acids displayed educational differences and were predictive of preterm delivery. Material factors (rented and crowded home) reduced the HR of preterm delivery for low educated women by 33%. The independent contribution of behavioural factors (smoking and alcohol consumption) from material factors was 5%, and the independent contribution of saturated fatty acids from material to behavioural factors was 4%. All these factors together reduced the HR of preterm delivery for low educated women by 42% (HR¼1.66, 95% CI 0.76 to 3.63). Conclusion This study is one of the first to attempt to explain social inequalities in preterm delivery comprehensively, and underlines the importance of material, behavioural and nutritional factors. More research is needed to better understand and prevent social inequalities in preterm delivery. P1-454 EXPLANATIONS FOR SOCIAL INEQUALITIES IN PRETERM DELIVERY IN THE LIFEWAYS COHORT
