WEIGHTS OF APPARENTLY WELL FILIPINO INFANTS VICTOR TANTENGCO. M.D., RUTH ALICE DAVIS * . M.D., M.P.U. * Visiting Assistant Professor from John Hopkins School of Hysteric and Public Health. Ind AMANDA VERGARA-VALENZUELA, M.D.. M.P.R. Institute of Hygiene University of the Philippines This study was primarily intended to provide weight standards for a study on mortality from diarrhea-enteritis among infants in Manila whose nutritional status needed to be evaluated. This paper ia an account of the methods used and the re­ sults of collecting weight measurements of children during their first year of life. Estrada and Cancio(l), conducted a similar study in 1951. They used a total of 2482 infanta enrolled in the Well Baby Clinic of the Department of Pediatrics of the College of Medi­ cine, University of Santo Tomas. Weight and height readings at birth, at 2 weeks and for every month of age thereafter up to 12 months were presented. We did not use their results for several reasons. First, we honestly believed we might be able to get measurements of children under two years of age to which age group the diarrhea study subjects belonged. Pre­ liminary examination of child records in two health centers revealed that there was a sad dearth of measurements beyond infancy: we had to abandon this plan. Secondly, it was felt that a more representative group of children than that served by one clinic could be studied. Sex specific measurements were also preferred as it was the intention to use the weight to help evaluate the nutritional requirements of each boy or girl in the original diarrhea study. Del Mundo and Adiao(2) published weights and heights as well as head and chest measurements of Filipino newborns. Again, we needed to have data beyond the newborn stage. It 215 216 ACTA MEDICA PHI LIPPIN A was, therefore, decided that data be collected for use in the enteritis project. MATERIALS AND METHOD The records of 836 infants from four hospitals and three health centers were examined and weight measurements from birth, at monthly intervals, to the 12th month of age were collected. A set of criteria was formulated and served as guide for the inclusion of infants in the study. The choice of well baby clinics and health centers was based on the availability of records. The project was originally planned to include babies up to two years; however due to the diminishing num­ ber of infants and children reporting to the clinics from the 7th month and after, it was deemed unnecessary to collect data, insufficient to be of any use, beyond the first year of age. The criteria for inclusion of an infant in the study were: 1. A well child one year of age or under: An infant free from illness during his lifetime, or a child with 1-2 days low grade fever, 6-6 mild respira­ tory tract infections, and/or 2 mild gastro-intestinal upsets during the year may be considered well. For determining the degree of severity of the infection of the respiratory tract, the occurrence and frequency of coughing and the duration of the illness are taken into account. A mild gastro-intestinal upset should not last more than 2-3 days, nor cause noticeable dehydration, loss of appetite or behavior changes. Measurements of the child can be utilized up to the time of occurrence of any severe illness. 2. Only infants born on or since January 1, 1952 would be included in the study, The year 1952 was arbitra­ rily set as we wanted to get as comparable a group of infants as we could to our diarrhea group who were bom within the last five years. 3. Gestation age of at least 85 weeks or a birth weight of at least 2275 grams or 5 pounds. 4. Each clinic record to be included must contain the fol­ lowing information: a. date of birth AVERAGE WEIGHT OF FILIPINO INFANTS 217 b, length of gestation or birth weight. If this is not in the child’s record, it may be in the mother’s chart If no information is available in the latter chart, a statement whether the child is full term or premature is made in the baby’s record. c. reasonably complete morbidity history of child for life span prior to each weight measurement. (The morbidity history may be summarized as a brief monthly evaluation by clinic physician or pediatri­ cian). The child may he considered well in the absence of health evaluation if such lack does not extend to a period beyond 3 months. Each baby may have one record for the well baby clinic and another for general clinic; in which case, both re­ cords have to be inspected. d. only weight measurements done on a beam balance would be considered. These need not be available for each month for each child. (Obviously only weights taken in the clinic, except birth weight, which may be taken upon home visit, were includ­ ed). A number of measurements taken by nurses during home visits had to be discarded as these were measured by instruments other than the beam bal­ ance in the clinic. If two weights were recorded in one month, we took the measurement with an al­ lowance of plus or minus 10 days taken closest to the last birthday; e.g. a child born on June 2, 1952 may be weighed July 10 and July 20; the weight taken on July 10 is used and recorded for one month of age. e. sex of child. Records of infants seen at the following hospital well baby clinics and health centers were'examined and used in the study: 1. Maternity and Children’s Hospital 2. Philippine General Hospital 3. St Luke’s Hospital 4. University of Santo Tomas Hospital 5. San Francisco del Monte Health Center 218 ACTA MKDICA PH1LIPP1NA 6. Novaliches Health Center 7. Rosario Reyes Health Center The number and percentage of infants and measurements, excluding birth weight, by source, for separate and combined sexes; and the median weights for each sex, according to age. are shown in the different tables. Table 1 shows a breakdown of the number and percentage of the infants by source of records. The number from hospital well baby clinics comprising 81.7 per cent of the total studied, outnumber by more than four times those from the health cen­ ters. By and large, the total number of deliveries from these hospitals far exceed those from the city and suburban health centers; hence, the greater number of records to choose from. Although health centers had many well kept records, several could not be used because they fell short of the requirements for inclusion of a record in the study.

Each child may have one, sometimes two or more measure­ ments taken at various intervals, which were utilized in the study. Hence, the measurements are neither strictly crossAVERAGE WEIGHT OF FILIPINO INFANTS 219 sectional for the group, nor longitudinal; but a combination of both. The original plan was to collect at least 100 measure­ ments for each month of age, but this did not materialise be­ cause of the decreasing numbers, of children reporting for check­ up during the second half of infancy.
