Abstract
The objective of this study was to assess weight changes over time in reproductive-age
women using nonhormonal contraception [copper intrauterine device (IUD) users]. Baseline
variables recorded included age, parity, decade when the IUD was inserted and the
presence of hypertension. A total of 1697 IUD users were followed for 7 years of use.
The mean age (± SD) of the women at the beginning of follow-up was 27.6 ± 5.8 years
and the mean height (± SD) was 150 ± 10 cm. The mean weight (± SD) at the time of
IUD insertion was 58.5 ± 0.30 kg. After 5 and 7 years of follow-up, the mean weight
(± SD) was 61.2 ± 0.33 kg and 62.4 ± 0.51 kg, respectively. At insertion, the body
mass index mean (± SD) was 24.5 ± 0.12 and after 3 years it was 25 ± 0.14, remaining
above 25 up to the 7th year of observation. During the 7 years of follow-up, older
women gained more weight than younger women. Parity, decade of IUD insertion and hypertension
were not noted to be significant determinants of weight variation. In conclusion,
this cohort of lower and middle class Brazilian copper IUD users tended to gain weight
during their reproductive life, independent of other factors. These observations may
improve counseling of women regarding the prevention of age-related obesity.
