Notes.

Model I: Number of strata = 38; Number of PSUs = 608; Number of observations = 4,416; Degree of freedom (df) = 570, F = 4.47, Prob > F = 0.000, P-value significant (shown in bold) if P < 0.05.

Bronfenbrenner’s social ecological model used as theoretical framework with three levels (Individual level, microenvironment level, macroenvironment level.

Hosmer-Lemeshaw goodness-of-fit test for logistic model: F(9, 562) = 0.8, Prob >F = 0.6.

Data used from 2014 Cambodian Demographic and Health Survey (CDHS).

There are 407 missing values in the variables “person to decide for respondent’s health care” and “person deciding about major household item purchase” in the dataset.
