Title: Lifecycle of Humans
Stages:
Preconception
Pregnancy
Infancy
Breastfeeding
Toddler
School-age
Adolescence
Adulthood
Elderly
Different nutritional needs at each stage
Preconceptional period:
Anytime before pregnancy
Time period of 2-6 months prior to pregnancy
Periconceptional period:
Period ranging from at least 2 months prior to conception through 4 months of pregnancy
Period ranging from 1 month prior to conception through 2-3 months of pregnancy
Continuum of critical periods:
Preconception
Conception
Postpartum
Delivery
Pregnancy
Periconception
1000 days of life: 2 years to 6 months, 2 months, 4 months
Importance of preconceptional nutrition for pregnancy outcome
Neglected issues in preconceptional nutrition
Most nutrition interventions focus on pregnancy only

Nutritional problems during preconceptional period
Anemia and other micronutrient deficiencies are prevalent among women in reproductive age
Chronic energy deficiency (CED) is also a common nutrition problem
Anemia is a condition of low hemoglobin level
Anemia has multifactor causes
Factors affecting anemia
Protein, heme synthesis, vitamin B complex, zinc, vitamin A, transferin, copper, iron, genetic factors, vitamin B12, bleeding, infection, parasites, inhibitor, kidney failure, erythropoiesis
Prevalence of anemia in Indonesia:
Infants: >70%
Pregnant women: 43%
Women in reproductive age: 29%
Prevalence of anemia in Indonesia by age group
Chronic energy deficiency (CED) defined as Mid Upper Arms Circumference (MUAC) ≤ 23.5 cm
Measurement method for CED
Prevalence of CED among women in reproductive age is about 30%
CED is greater in rural and suburban areas compared to urban areas
Low energy and protein intake contribute to CED
Poor nutrition during preconception can lead to:
Low birth weight
Pregnancy complications such as pre-eclampsia, pre & postpartum hemorrhage, premature delivery, miscarriage
Determinants of low birth weight in developing countries
Nutritional factors play a role in low birth weight
Intergenerational cycle of low birth weight
Effects of low birth weight on different stages of life
Low birth weight can be categorized as premature or intrauterine growth retardation (IUGR)
Maternal malnutrition is a major cause of IUGR in developing countries
Premature delivery defined as babies born ≤ 37 weeks of pregnancy
Early preterm: born < 35 weeks
Late preterm: born 35-37 weeks
Maternal size (anthropometric) as a predictor for birth weight
Four maternal components derived from pre-conception anthropometric measurements:
Weight
Height
Fat mass (calculated from skinfolds)
Muscle mass (calculated from arm muscle area)
Prepregnancy weight can be used to predict low birthweight.
In a US study, women with a prepregnancy weight below 59 kg were more than twice as likely to have LBW infants compared to women with prepregnancy weights >59 kg.
Prepregnancy weight of less than 40 kg is a useful cutoff to predict women who will deliver low birthweight babies.
Tripathi, et al. (1987) found that 60% of small-for-date Indian infants had mothers with prepregnancy weights less than 40 kg and a weight gain of less than 5 kg.
Anderson (1989) estimated that Indian women weighing less than 40 kg during the first 6 months postpartum had twice the risk of delivering low birthweight infants.
Weight gain in the second and third trimester is of greater importance for ensuring fetal growth than weight gain during the first trimester.
Maternal height predicted neonatal length.
Maternal fat mass predicted neonatal skinfold thickness.
Intervention to promote optimal fetal growth:
Nutritional health care
Health-related behavior
Infection control
Nutritional intervention:
Food (nutrient) supplement
Nutrition education
Food supplementation during preconception aims to prepare the body's stores for the increasing need of nutrition during pregnancy.
Food supplementation during pregnancy aims to prevent low birth weight and not promote fetal overgrowth.
Fe supplementation interventions throughout the life cycle:
Infancy
Pre-school children
School children
Adolescence
Pregnancy
Pre-pregnancy
Strategic entry points for Fe supplementation:
Intervention Fe syrup in selected areas
Intervention: school feeding
Intervention among senior high school students
Daily Fe supplementation
To make body iron store prior to pregnancy
Existing programs for Fe supplementation:
Suplementasi tablet besi dosis: Kel. Sasaran WUS & remaja putri
Frekuensi 1x/mg selama 16 mg, 10 hari selama mens
Dosis Pencegahan 1x1 tab
Dosis pengobatan 3x1 tab
1 tab (200 mg fero sulfat) mengandung 60 mg Fe, 0,25 mg Folat
1 sendok sirop mengandung 30 mg Fe
Multi micronutrient (MMN) supplementation:
MMN supplementation for pregnant women in developing countries (Indonesia: Lombok Tengah, Sika, Belu, Klaten; other countries: Nepal, Mexico, Zimbabwe)
MMN contains a daily dose of 15 vitamins and minerals, including retinol, vitamin E, vitamin D, vitamin B1, vitamin B2, niacin, vitamin B6, vitamin B12, folic acid, vitamin C, iron, zinc, copper, selenium, and iodine
Tasks related to preconceptional nutrition:
Preconceptional nutrition & LBW
Preconceptional nutrition & preterm
Preconceptional nutrition & pre eclampsia
Preconceptional nutrition & anemia/iron deficiency
