Methods: A follow-up study with 7, 872 couples was conducted from 1987 to 199o beginning from the time they got marriage licenses in two districts defined in Shanghai. They were interviewed in the third month and again in the fifteenth month and in the fifth to sixth year afterwards individually at home. The total follow up rate reached 98%. Couple’s background characteristics as well as the information on their general health. reproductivc history and contraceptive use etc.. were collected dynamically. All of the single live births with term delivery were Included for data analysis in this paper. Adjusted odd ratios and population attributable risk (PAR%) were computed. Results: The prevalence of TLBW in Shanghai single term live births was 2. 0% (134,/6.573), represents 54. 7% (134/245) of the total low birth weights in our sam pie. Significant social and behaviour risk factors relating with TI-BW were wife’s dissat- isfaction with marriage; low education level of husband; co-residence with parents during pregnancy; heavy housework done by the wife while being pregnant. Significant biomedical risky factors were menarche age greater than 16 years old; maternal age at delivery greater than 29 years old; maternal body mass index less than 19. 8; wife suf- fered from serious disease prior to conceiving; having pregnancy complication; gestational weight gain less than 20 % of pre-pregnancy weight; having abortion, stillbirth and fetal death history. Conclusion: TL.BW constituted over half of all low birth weights in Shanghai. Special attention should be paid to the determinants mentioned above in TLBW intervention program. Improving couples’ economic and living condition and husband ’s education at tainment, and caloric supplementation with women while being pregnant would all be particularly effective in reducing the occurrence of TLBW in Shnaghai.展开更多

Both quant itative and qualitative research approaches were used. This report mainly deals with the quantitative data. Qualitative data provided insights into the behavior of breastfeeding and contraceptive use, which helped to understand the percepti ons and behavior of people and community in this area. Information was obtained from 496 new parturient women who gave birth in the five district hospitals wher e they first were interviewed. They were then followed-up three timings for int erview at 42 days, four months and one year after delivery, respectively. Struct ured interview questionnaires filled out by trained interviewers. Total subjects of 492 women were for analysis in this paper.Results: The results showed that 74.4% of women were using contr aceptive methods when they resuming the first sexual activity after delivery. Du ring postpartum period, the majority of women interviewed used condom within 3 m onths, for instance, at 3 months after delivery, there were still 84.5% of women use condom. Afterwards, most of them switched to IUD. Life table analysis shows that the continuation rates of full breastfeeding, abstinence, amenorrhea and a cceptance of contraceptive methods at 4 months after delivery were 35.5%, 68.2%, 5.0%, and 86.3%, respectively. Conclusion: The policy implications of this study are that contr aceptive services and information for postpartum women in urban areas need to be improved further. The contraceptive methods providing for postpartum women shou ld have more methods to let women choose and instead of only one method for all of postpartum women.展开更多
