Abstract: A. survey was made in rural population of Jiamusi to study socioeconomic factors in intestinal parasite infection. The result showed that the infection rate for intestinal parasites was 21.8%(553/2 634), which was much higher(45.6%)in people below the age of 14 years than above(16.5%)(x2 = 659.57, P0.01). The infection rates were respectively 52% in pupils, 25% in preschool children and 17.3% in farmers. Statistical ana-ysis of various socioeconomic factors revealed that the highest parasite infection rate was indicated in residents with low family income and inferior cultural level; in addition, sanitary environmental conditions and personal hygiene were important subsidiary factors. Improvement of personal hygiene and environmental sanitation in parallel to parasiticide therapy were suggested as the fundamental control measures.
