However, epidemiological studies specifically referred to LPTA in the last months of pregnancy are scarce. We evaluated the association between LPTA and the risk of both preterm delivery and small for gestational age (SGA) during the last three months of pregnancy in Italy. A nationwide case-control study was performed in nine Italian cities. A total of 299 preterm delivery, 364 SGA and 855 controls were enrolled in the study. A self-administered questionnaire was used to assess socio-demographic variables, medical and reproductive history, life-style habits and LTPA referred to the last three months of pregnancy. Univariate and multivariate regression analyses were performed in order to estimate Odds ratios and 95% CI. LTPA during the last three months of pregnancy decreases the risk of preterm delivery (adjusted OR = 0.56;95% CI 0.39 - 0.79). Among the different types of physical activity, walking, the most frequently referred activity, appears significantly protective against preterm delivery (adjusted OR = 0.53;95% CI 0.36 - 0.81). Moreover, a small protective effect of walking was evidenced against SGA (adjusted OR = 0.72;95% CI 0.51 - 1.00). In conclusion, a mild physical activity such as walking in the last three months of pregnancy seems to reduce the risk of preterm delivery and, at a lesser extent, of SGA, confirming the beneficial effects of physical activity along the whole pregnancy.展开更多

PURPOSE： To verify the impact of adding leisure-time activities to the existed sedentary behaviors. METHODS： A cross-sectional and a longitudinal analysis were undertaken in an ongoing epidemiological study （＂Move for Health＂） conducted by this Institution. The longitudinal study comprised 1572 subjects older than 35 yrs （53.8 ± 11.1 yrs, 76% women） enrolled during the period of 2004 to 2015. After a baseline assessment, the participants were submitted to a 10-week program of supervised physical exercises training and dietary counseling. The physical exercise protocol was composed by daily sessions （100 min）, 3-5x/wk, including warm up/stretching （20min）, 30 rain walking （60%-80% VO2max）, 40min strength in academy （3x 8-12 rep, 60%-70% 1RM） and stretching and cool down （10 min）. By using the International Physical Activity Questionnaire （IPAQ-way long-version 8）, it was evaluated the time spent on sedentary activities during the week and on weekends （h/day）, in the domains of sedentary transport （h/week） and physical leisure activities （h/week） at baseline （M0） and after 10 weeks （MI） of physical intervention. The Student＇s t test was used to compare moments with a significance level of 5%. RESULTS： I was shown that 18.3% presented lower values than 150 min/wk of physical activity. Lower quartile of leisure domain on weekdays along with more sedentary behavior on weekends were determined by socioeconomic characteristics such as lower income and schooling. The sample referred low income （71% earning less than 5 minimum salary wage）, low schooling （52.6% uncompleted elementary school） but in a good-excellent status of health, according their self-perception. Leisure time-physical activity increased 2.12 （P 〈 0.001）. Behaviors of sedentary transport and sitting time either weekdays or weekends did not change significantly （P 〉 0.05）. CONCLUSION： An inexpensive and institutional-conducted lifestyle modification program like the ＂Move for Health＂ can provide extra energy expenditure, as leisure time, to a low socioeconomic community. However, it has been unsuccessfully proved to change other existing sedentary behavior.展开更多
