Conducted by a team of researchers from the United States and the Philippines, the Cebu Longitudinal Health and Nutrition Survey is part of an ongoing study of a cohort of Filipino women who gave birth between May 1, 1983 and April 30, 1984. The CLHNS was originally conceptualized as a study of infant feeding patterns, particularly the overall sequencing of feeding events (i.e., of both milk and non-milk items), the various factors affecting feeding decisions at each point in time, and how different feeding patterns affect the infant, mother, and household. The idea was to study these topics within as natural a setting as possible and to analyze how infant feeding decisions by the household interact with various social, economic, and environmental factors to affect health, nutritional, demographic, and economic outcomes. The cohort of children who were born during that period, their mothers, other caretakers, and selected siblings have been followed through subsequent surveys conducted in 1991-2, 1994, and 1999. DSS has select years.
