1. Public Nutrition: Policies and Programs INHL 613 Tues – Thurs 3.00 – 4.40 12 Jan – 2 Mar 2010

2. Course. • Principles and introduction • Community-based Health and Nutrition Programs • Micronutrient Programs • National planning exercise.

3. Introduction • What are nutrition and public nutrition? • Consequences of malnutrition (hence: why bother?) • Causes of malnutrition to tackle (what to do about it?) • Brief epidemiology • Context and program principles

5. What does ‘nutrition’ cover? Consequences … • For children: • Health (direct and risk factor – see DALYs) • Survival/mortality risk • Intellectual development, educational result • Nutritional status (micronutrients, growth – affects future earnings) • For women: • Health (direct and risk) • Reproduction, intra-uterine development in pregnancy • Nutritional status (especially anemia) • For all: • Health • Activity, productive and discretionary • Freedom from hunger • These apply to undernutrition and obesity: we deal mainly with undernutrition.

18. What does ‘nutrition’ cover? Causes and interventions. • See various frameworks, e.g. UNICEF – proximal causes: • Poverty and food security • Health environment, access to services • Care … • (Converse of hunger, sickness, and neglect) • These interact and have important feedback loops (e.g. see malnutrition-infection spiral). More distal causes often are contextual rather than intervenable upon. • Time and biology are crucial – intra-uterine development (even at conception) has major influence (even on next generation). • Context, and program interventions: context determines whether interventions are effective; often cannot be quickly changed. • Single interventions are of well-known effectiveness, but they also importantly interact and have feedback loops. Issues are HOW to sustainably support them, and combine them.

34. Context

42. Program Intervention and Context A. In unfavourable context, program intervention for the individual has limited effect

43. Program Intervention and Context B. In better context, program intervention for the individual has much more effect

44. Program Intervention and Context C. In highly supportive context, improvement is endogenous and program intervention gives additional effect
