Background: The high rates of rapid urban and economic growth occurring in Asia are bringing about parallel changes in both food consumption patterns and nutritional status. Aim: The aim of this study is to examine the impact of these changes on the nutritional and health status of mothers and their offspring in Vientiane, Lao PDR. Methodology: Over 2 consecutive years, a follow-up study of 150 infant-mother pairs living at three different levels of urbanization was performed in Vientiane. The mothers completed a questionnaire on their eating habits. Clinical examinations and anthropometric measurements were also carried out. Results: The results showed that, in general, the dietary energy content was low (providing only 83% of the energy requirement) and there were deficiencies in calcium, vitamin A, Folate and iron. The main energy source was rice (providing 40.9%), while 40% of the protein provided by meat and fish provided 19.8%. The differences observed in the food contribution to energy intakes and in food diversity varied with the level of urbanization. The prevalence of stunting (13.9%; CI 10.0∼18.6%) was less than that reported at the country level. Stunting was related to age, the sex of the child and the mother's physique and varied according to the level of urbanization. Conclusion: The level of urbanization in Vientiane influences the pace of the ongoing process of nutritional transition.
