Individual Food Consumption/Dietary Survey [hh/ifcs]
Conducted by a team of researchers from the United States and the Philippines, the Cebu Longitudinal Health and Nutrition Survey (CLHNS) is part of an ongoing study of a cohort of Filipino women who gave birth between 1 May 1983 and 30 April 1984. The CLHNS was originally conceptualized as an interdisciplinary study of infant-feeding patterns, particularly focusing on the overall sequencing of feeding events (milks and complementary foods), on the factors affecting feeding decisions and on how feeding patterns affect the infant, the mother, and the household. The study was subsequently expanded to cover a wide range of maternal and child health as well as demographic issues that could be well studied using a prospective, community-based sample.
The cohort of children born during the 1983-1984 period, their mothers, other caretakers, and selected siblings were interviewed for the first time in the 1983-1986 survey and have been followed through the surveys conducted in 1991-1992, 1994, 1998, 2002, 2005, 2012, and 2015. The 1998 survey added a focus on adolescent reproductive health and sexual behavior and measured physical activity using questionnaires as well as an objective measure (Caltrac). Blood pressure measurements in adolescents and mothers were also added. For the mothers, memory tests and questionnaire modules on physical functioning were added.

Sampling
At the baseline survey conducted in 1983, a single-stage cluster-sampling procedure was used to randomly select 17 urban and 16 rural barangays from the 243 barangays of Metro Cebu identified in the 1980 census. The selected barangays, representing approximately 28 000 households, were surveyed to locate all pregnant women, who were asked in person to join the study. The 1998 survey was a follow-up of the mothers enrolled at Baseline and their children born between 1 May 1983 and 30 April 1984 (birth cohort).
No survey weights were used in this survey.

The methods used to collect the 24-hour dietary recall data were designed to reflect standard practice and were not validated in the sample. Participants in the study were asked to recall each food they had eaten the previous day from the time they woke up to the time they went to bed. Prompts were included (e.g., "before breakfast", "breakfast", "morning snack", "lunch") to help participants recall each individual meal and snack. Meals and snacks eaten outside of the home were also recalled and recorded. To provide complementary information about the reliability of the 24-hour dietary recall, participants were asked to indicate the usual number of meals eaten, usual food items and whether meals on the recalled day represented "usual" intake. "Usual" was defined as occurring at least three to four times a week.
