Abstract
Objective To introduce the basic design, development plan and objectives of a population-based birth cohort in Shanghai, and further present the main data and baseline characteristics of enrolled participants in the cohort, and to provide key information for reproductive health-related studies.Methods The Shanghai population-based birth cohort initiated on January 1, 2005, included newborns born in Shanghai every year and their parents, and collected information on reproductive health, reproductive treatment, birth characteristics, growth and development status, as well as the incidence, treatment and death of diseases by employing data linkage technology and investigations. This formed a birth cohort spanning the entire life cycle.Results As of October 2022, a total of 2 978 538 newborns and their parents were included in the cohort. Among them, 2 905 135 (97.54%) were naturally conceived (NC), and 73 403 (2.46%) were born through assisted reproductive technologies (ART). The average age of parents was (32.56±4.12) years old for females and (34.62±5.34) years old for males in the ART group, which was higher than (28.02±4.71) years and (30.07±5.54) years for parents in the NC group. Among parents, females and males aged 30 and above accounted for 77.12% and 85.08%, respectively, which were higher than that of parents (35.28% for females and 49.66% for males) in the NC group. Furthermore, the percentage of parents with a college degree or above in the ART group was 73.23% for females and 73.66% for males, which were higher than those in the NC group (49.98% and 50.91%, respectively). The multiple births rate in the ART group was 33.81%, which was higher than that in the NC group (1.88%). The incidence of premature birth and low birth weight in the ART group were 24.47% and 19.08%, respectively, which was higher than that in the NC group (5.47% and 3.73%).Conclusion The comprehensive collection of reproductive health-related information in the birth cohort in Shanghai can provide essential resources to determine the influence of genetics, environment, reproductive treatment and other related factors on the health of offspring after birth.
