The impact of household and community risk factor on labor force aged mortality in Nang Rong, Thailand
Abstract:
This study examines the influence of household and community risk factors on
labor force aged mortality in rural areas of the Northeastern region, Thailand. The
investigation observed the main effect of both social context as measured by
household factors and community variables those are related to the exposure to
disease factors and the resistance to disease variables on various causes of death.
To explore and measure the size of the effect, the examination employed
longitudinal data from Nang Rong Project between 1994 and 2000. The unit of analysis
was population who were among the labor force aged between 13 and 60 years old in
1994, who become persons aged between 20 and 67 years old in 2000. Total samples
were 28,298 cases. According to this sample size, there were 634 cases who died
during 1994 to 2000. Thus, 27,664 cases survived. For this reason, the survival analysis
under the method of piece-wise exponential hazard model with left truncated was used.
There were sixteen independent variables, which were divided into 3 groups. They
were demographic characteristics, household factors and community contexts.
Dependent variables were measured by causes of death and classified into 4 groups: 1)
communicable diseases; 2) non-communicable disease; 3) accident/external causes; and
4) maternal causes. Furthermore, the study also employed the Verbal Autopsy method
to examine the accuracy of for the claim cause of death.
The major causes of death were mostly from non-communicable disease,
accident / external causes, and communicable disease respectively. It was important to
note that none of the individual died from maternal causes. From household risk
factor analysis, household sanitation and household density had some effects on
mortality. For example, when the number of household members increased, the
hazard of dying increase. When considering community risk factors, the community
density and the number of health personnel in the areas had an effect on mortality.
For instance, when population in community increases, the hazard of dying increases.
In addition, when number of health personnel increases, the hazard of dying deceases.
