Abstract

Background: The use of contraception tool is one of the factors that affect fertility. It is influ­en­ced by demographic, socio-economic, legal, political and environmental factors. The use of mo­dern family planning method can provide optimal benefits by minimizing side effects and complaints felt by the community. The aim is to analyze the determinants of the use of modern fa­mily planning method in Malinau District, North Kalimantan by using the theory of planned behavior. Subjects and Method: This was an observational analytic study with cross sectional appro­ach conducted in 4 (four) sub-districts in Malinau District, North Kalimantan, in December 2018 to January 2019. Total 200 subjects were selected by fixed disease sampling. The de­pen­dent variable was the mothers who applied the modern family planning method. The inde­pen­dent variables were maternal age, parity, area of residence, level of education, family income, per­ception, intention, attitude, and subjective norms. The data were collected by question­nai­res and analyzed with path analysis. Results: The use of modern family planning method in women is directly and positively influ­en­ced by parity ≥ 4 (b = 3.03; 95% CI = 1.23 to 4.83; p <0.001), high family income (b = 4.57; 95% CI = 2.66 to 6.47; p <0.001), positive attitude (b = 3.92; 95% CI = 1.42 to 6.42; p = 0.002), and strong intention (b = 4.84; 95% CI = 2.85 to 6.82; p <0.001). The use of modern fa­mily planning method for women is indirectly influenced by the level of education and sub­ject­ive norms. Conclusions: The use of modern family planning method in women is directly and positively influenced by parity ≥ 4, high family income, positive attitude, and strong intention. The use of modern family planning methods for women is indirectly influenced by the level of education and subjective norms.
