T he prevalence of increased body weight in injecting birth control acceptors is79.8%, this has an impact on body health, namely heart disease and stroke, heartfailure, high blood pressure, dyslipidemia and metabolic syndrome. The durationof use of DMPA injection contraception can affect weight gain because thehormone progesterone in DMPA stimulates the appetite control center in thehypothalamus. The purpose of this study was to determine the relationship betweenduration of use of DMPA contraception and increased body weight in DMPAinjectable birth control acceptors.METHODSThis research is an analytic observational design with a cross-sectional approach.The population of this study were family planning acceptors with a sample ofDMPA injecting family planning acceptors at the Pangkalan Health Center. Thesample selection technique uses consecutive non-random sampling. Data wereobtained through family planning acceptor cards and interviews. Data wereprocessed and analyzed using the Chi-square test and Fisher's exact test.RESULTSBased on the results of the study on 69 respondents, there was a significantrelationship between the length of time using DMPA injection contraceptives andan increase in body weight at the Pangkalan Health Center (p=0.000). There was asignificant relationship between the age of DMPA family planning acceptors andincreased body weight (p=0.028). There is no relationship between education andparity of DMPA family planning acceptors with increased body weight (p=0.615and p=0.188).CONCLUSIONSThere is a significant relationship between duration of use of DMPA injectioncontraception and age of family planning acceptors and weight gain at thePangkalan Health Center. There is no relationship between education and parity ofDMPA family planning acceptors and weight gain.
