The study area was conducted in Kapor district in Ranong province by interviewing 232 Buddhist Thais and 120 Muslim Thais aged over 60 years. The data were analyzed statistically and the results were compared between the two groups of the elderly from the different religious backgrounds. The results were divided into three parts: demographic characteristics and well being, a structural comparison of the health-oriented social support network, and a comparison of functional social support on health based on the perceptions of the elderly. The study findings revealed that different religious beliefs did not affect health-based social supports despite different practical principles and methods, because both religions teach younger generations to treat the elderly in the same way. Statistically significant social networks of the elderly were as follows. The size of social networks of the Muslim elderly was larger than that of the Buddhist elderly. Family and relative networks of the groups received more support from their female children than from their male children. Children living in other provinces of the Buddhist elderly came to visit them more often than those of the Muslim counterparts. Finally, the elderly received social support from neighbors who were younger or of the same age and had similar family status to the elderly.
