Technical Meeting on the Diet and Eating Practices of Adolescent Girls and Women

March 16 – 17 2015 PAHO/WHO, Washington, DC

Some background on rationale for this technical meeting

• The 2013 Lancet Series on Maternal and Child Nutrition provided new evidence on the importance of the nutrition of women at the time of conception and during pregnancy, not only to ensure optimal fetal growth and development but also for the health of the mother.

• The series also identified adolescent girls as a key priority and highlighted the importance of a life course approach, placing them together with women of reproductive age and mothers at the center of nutrition interventions.

• Despite the recognized importance of adolescent girls’, women’s and maternal nutrition for their health and that of their children, this group is virtually neglected in nutrition programming with the exception of provision of iron and folic acid supplements during pregnancy.

Background/rationale (cont.) • In 2012, there were 1.2 billion adolescents in the world – defined as

young people between the ages of 10 and 19 years. • The vast majority of adolescents (90%) live in low- or middle-income

countries (LMIC). In some countries, as many as half of all adolescents are stunted, with impact on physical and cognitive development

• About 16 million girls aged 15 to 19 and some 1 million girls under 15 give birth every year—most in LMIC. Complications during pregnancy and childbirth are the second cause of death for 15-19 year-old girls

• Alarming shift in BMI globally - growing rates of overweight and obesity in many LMIC. (Throughout LAC, the prevalences of overweight and obesity is around 50%. This is also true for Central and Eastern Europe.)

Meeting Objectives

1. Review insights and lessons learned from two discussion papers commissioned by SPRING

2. Identify characteristics of and issues related to key diet and eating practices for strengthening policies and programs for adolescent girls’ and WRA’s nutrition

3. Propose next steps in development of a set of key diet and eating practices

Began by reflecting on the Guiding Principles:

Goal: To develop a set of unified, scientifically based guidelines that could be adapted to local feeding practices and conditions

This earlier review provided the scientific basis for 9/10 principles

(active feeding not evidence based)

Target audience: Policy makers, program planners, health care providers and community leaders

WHO Evidence-Informed Guideline Development Process

Countries have been proliferating Food-Based Dietary Guidelines for about 20 yrs

FAO recently launched an on-line repository of ~100 country FBDGs and associated resources.

A “descriptive summary” project by Mary Arimond, Jennie Coats and Anna Herforth.

Objectives of Background Paper #1: Nutrition of Adolescent Girls and WRA

• Present the current landscape of nutritional status of adolescent girls, women of reproductive age, women during pregnancy and during lactation

• Summarize potential key

nutrition actions and interventions to improve nutritional status of these population groups

Objectives of Background Paper #2: Review of Programmatic Responses

• Conduct a rapid review of the literature & programmatic documentation to: Provide information on global

programmatic experiences to improve the nutrition of adolescent girls and WRA

Summarize inputs, outcomes, and lessons learned from implementers who have/are carrying out nutrition programs

Some Key Findings • Reducing short maternal stature requires continued

improvements in nutrition lifecycle of girls. • Key nutrition interventions include support for

maternal nutrition during pregnancy and lactation, IYCF and development of healthy eating patterns.

• Nutritional interventions during later childhood

and/or adolescence need study (efficacious?). • Family planning to delay age at first pregnancy

likely contributes to improving maternal stature.

Key Findings (cont.)

• The nutritional status of WRA has shifted over time, with some reductions in the prevalence of underweight, and shifts from normal weight to overweight/obesity.

• The problem of underweight

at the national level is less 10% in all areas except for some parts of Sub-Saharan Africa, and South Asia.

Key Findings (cont.)

• The problem of under-weight among adolescent girls, particularly those 15-19 is less well characterized, but appears to be consistent with those of women 20+, except in South Asia where it may be as high as 40%.

• In South Asia, there is urgent need to address the problem of underweight among girls and women.

Key Findings (cont.)

• When examined by age, overweight and obesity increased among women 20-30, suggesting postpartum weight retention as an explanatory factor

• There is a need to characterize

BMI status for local programming; in most areas the goal of having normal BMI means weight loss rather than weight gain.

Key Findings (cont.)

• Postpartum weight management is needed.

• Progress has been achieved in reducing maternal deficiencies of vitamin A and iodine, as well as anemia, but the problems remain.

• Inadequate zinc intake in LMIC appears significant.

• Folic acid fortification coverage is not optimal

Key Findings (cont.)

• Average nutrient intakes are inadequate in LMIC across regions and target groups. Importantly, adolescent girls, WRA and pregnant and lactating women do not face dietary concerns distinct from one another in terms of imbalanced macronutrient intakes, and inadequate micronutrient intakes

• More studies are needed and a comprehensive

strategy for nutrition during lactation is needed • Improvements in nutrient intake need to be placed

within the context of overall weight management.

Key Findings (cont.)

• Promotion of nutrient dense foods or foods providing key nutrients within the context of weight maintenance or loss (shift in consumption) is different from promotion of greater food intake (of the same or greater nutrient density) within the context of increasing BMI to normal.

• The relative effectiveness of interventions to reduce

“unhealthy foods” (e.g., sugar-sweetened beverage) consumption and/or increase consumption of “healthy foods” requires research in LMIC.

Goals for Diet and Eating Practices

Achieve normal weight • Low maternal BMI is a widely accepted risk factor for poor

pregnancy outcomes • For underweight women, it sets up a recommendation for

higher gestational weight gains that may not be achievable • Entering pregnancy overweight/obese increases the

likelihood of complications, including fetal demise • For overweight women, gestational gain and postpartum

weight retention contribute to obesity Maintain or improve diet quality as a lifestyle goal • Adequate intakes of calcium, iron, vitamin C, vitamin A, folic

acid, whole grains, vegetables and fruits, reduce alcohol intake

Goals for Diet and Eating Practices (cont.)

Maintain or improve physical activity level/active lifestyle • Important since physical activity tends to decline during

pregnancy, and starting new physical activity is not recommended)

Other • Prevent/treat anemia and achieve adequate iron stores • Maintain sufficient iodine intake to avoid thyroid disorders • Maintain sufficient vitamin A intake to maintain retinol

concentrations; • Ensure folic acid intake of 400 ug/d

Some Gaps in Evidence

• In places where you have women of low BMI (South Asia, West/Central/East Africa), what is the evidence around the efficacy of interventions to increase BMI on women entering pregnancy with low BMI?

• “Eating down” during pregnancy to avoid a large baby – is the practice less common than the concept?

• Catch-up growth in adolescence – what is the contribution of animal source foods?

• What is the efficacy of dietary guidelines - do they actually change behaviors?

• Can the balance within meals and the timing of meals avoid spikes in blood sugar levels, macronutrient and caloric intake

• What are the determinants of dietary behavior? • What is the impact of marketing of products to adolescents?

Outcome: Draft set of food based-practices or principles for an optimal diet - adolescents

Whole grains cereals and legumes (over highly refined grains*) Eat appropriate portion sizes (population & BMI specific /balance

energy intakes with energy needs, balance types of foods) Limit sugar & sweetened beverages Limit salts, salty condiments, salty snacks (iodized if salt is added) Limit highly refined and ultra processed foods Drink potable water Safe storage, preparation, and handwashing Moderate consumption of animal flesh and animal source foods*

(iron, zinc, b12, calcium, vitamin D, etc.) Separate recommendation for adolescent girls and perhaps WRA Fruits/vegetables (include dark green leafy & yellow/orange flesh) Distinguish legumes vs dark green/vegetables Eat a variety of foods Oil (placeholder – needs further development) Avoid skipping meals, eat breakfast
