Annex: Maternal anthropometry as a risk predictor of pregnancy outcome: the Nutrition CRSP in Mexico.

摘要: Introduction The analyses presented here employ data collected by the Mexico Nutrition CRSP research project in six villages rural Solis Valley of central during 1984-86[1, 2]. This was a joint scientists at Mexican Instituto Naciona de la Nutricio Salvador Zubiran and University Connecticut USA, funded 1982-87 1989-92 U.S. Agency for International Development. longitudinal study effects dietary intake on range human functions, including birth outcome, results which are summarized here. Analyses based 76 pregnancies. Subjects focused (1) pregnant mothers their subsequent infants (followed till 8 months age), (2) pre-schoolers aged 18 12 months), (3) children 7-8 years (4) parents households selected children. were enrolled, when available, from target communities represent nearly all who qualified to be communities. Pregnant women identified several ways: - newly enrolled tested pregnancy time family's enrolment; testing conducted every 3 children; screening high-risk done one community increase sample size. Maternal anthropometty. Anthropometric members under supervision Dr Julia-Beatriz Castillo. Measurements included weight (to nearest 0.1 kg), height or length (0.1 cm), head upper arm circumference triceps, biceps, subscapular supra-iliac skinfolds cm). Anthropometry measured non-pregnant months, month. Pregnancy outcome. Infant anthropometry within days birth, 30 days, other times until age eight months. Other outcome information recorded physician, type delivery (vaginal caesarean section), (live, still, spontaneous abortion), any complication. did not carry out Dubowitz testing, so database contains no estimate gestational infant birth. Table 1 shows correlation coefficients various maternal anthropometric measures. Of measures, body mass index show highest associations with weight.
