Objectives• To evaluate if an intervention of multiple

micronutrients (MMN) and early stimulation (play & communication) enhances child development

• To facilitate scaling up by using village level workers and Anganwadi Centers– Background– Theory– Design– Management– Implementation and status

2007 Lancet Series on Child Development

• More than 200 million children under age 5 years in low- and middle-income countries do not reach their developmental potential

• Major risks for poor child development– Chronic undernutrition – Nutritional deficiencies (iron, iodine)– Lack of stimulating opportunities

• Evidence on effective early interventions

2011 Lancet Series on Child Development

• Inequality in early childhood: risk and protective factors for early child development. – Reviews new evidence on:

• causes of developmental inequality• effective interventions to promote child development

• Strategies for reducing inequalities and improving developmental outcomes. – Priorities for early childhood policies and programs to

reduce inequalities – Estimates the cost of not investing in early childhood

The developing brain

• The brain develops through dynamic interactions of genetic, biological, and psychosocial influences and child behavior

• Exposure to biological and psychosocial risks (toxic stress) leads to deficits in brain structure and function, and pervasive impairments in educational outcome, mental and physical health, and overall well-being

• Disparities increase with early, multiple, and cumulative risks

Page 11: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

Iron Deficiency• Most prevalent single nutrient deficiency in the

world– ~35%– Leading cause of anemia– Associated with deficits in motor, cognitive &

socioemotional behavior– May affect brain functions

• Myelination• Dopamine• Norepinephrine metabolism

Psychosocial risks

• Lack of learning opportunities and poor quality caregiver-child interaction – major risk for poor development

• Brain architecture develops in the context of relationships

• Protective influences that promote child development– responsive caregiver-child interaction– opportunities for young children to play and learn

Page 14: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

Nutrition and health are necessary, but not sufficient for early child

developmentSubstantial gains in children’s development require:•Improvements in parenting, stimulation and early education

•Reductions in stressful experiences through psychosocial support for children and families affected by societal violence

Distal threats and opportunities reach the child through proximal interactions between child & family

Formative Phase

• Ensure culturally and developmentally appropriate material, messages, and methods

• Focus groups• Consultation with village workers and leaders• Mothers wanted children to be smart – thus the title

“Grow Smart”

Assessed Acceptability of MMN

When mixed with 50g (1 fist) of soft and smashed rice with pulse or milk, MMN formulationacceptable:

Assessed Feasibility of Play/Communication Intervention

Feasibility of play and communication intervention assessed to be high, based on pilot testing and consultation with other agencies

Page 22: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

Formal Approvals

• Approvals obtained from:– National Institute of Nutrition, India– Institutional Review Board, University of Maryland– Health Ministry Screening Committee, India– India Council of Medical Research– Department of Women and Child Development, India– Local village leaders – Local Anganwadi Centers

Page 23: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

Conclusion

• An intervention trial using local village level workers (VLW) to promote nutritional status and child development through MMN and a play/communication intervention delivered in the home for infants and AWC for preschoolers is:

• needed• acceptable• feasible• approved

Intervention Strategy

• Infancy Phase– Home Visits

• Nutrition Intervention (MMN messages) – Universal• Play and Communication Intervention – Randomized• Distribution of MMN/Placebo sachets (blinded)

• Preschool Phase– Anganwadi Center

• Government-sponsored childcare centers, food • Nutrition Intervention (MMN messages) – Universal• Distribution of MMN/Placebo food (blinded)• Quality determined by ECERS – Early Childhood Environmental Rating

VISIT 7 Play peek- a- boo with your child

Page 28: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

VISIT 7 (age 9-11)NEW MESSAGE: Play peek- a- boo with your child (SHOW PICTURE)

EXPLANATION: [CHILD] will love to play games with you. Remember [CHILD] is always learning. Things that seem simple to you will be amusing as well as rewarding to the child. Play games like peek-a-boo and clapping hands with your child. He will enjoy it immensely and will learn to play with others as well. ACTIVITY: •Using your hands or the pallu of your sari to cover and uncover your face. Tell [CHILD] ‘Here I am’ when your face is uncovered. Vary where you reappear (to the left, right, top, bottom).•Place [CHILD] in front of a mirror. Put a piece of cloth between her face and the mirror and then remove it. Repeat the action, so the child appears and disappears, while saying “Where is [CHILD]?”. DEMONSTRATE AND PRACTICE ACTIVITIES (PRAISE, PROBLEM SOLVE, ENCOURAGE) CHECKING QUESTIONS: •What games are you familiar with? When do you play them? How does your child react?•When can you and your family play these types of games with your child? MOTIVATION: Your child will enjoy interactive games. She will laugh and develop a sense of presence and absence, as she anticipates where you will appear. These activities will help her learn to focus and she will feel good about playing them with you and good about herself. The games will help her attention span so she can focus on learning.

Nutrition Intervention

• Flip Charts• Informed by:

– Indo-US Study (Vazir, 2012)

Reminder

Give dark green or orange vegetables and fruits daily

Page 31: Maureen Black, Ph.D. Sylvia Fernandez  Rao , Ph.D. Kristen Hurley, Ph.D. Shahnaz Vazir , Ph.D

VISIT 10REINFORCE MESSAGE: Give dark green or orange vegetables and fruits daily or as often as possible (SHOW PICTURE)

FLIP CHART ACTIVITY (SHOW PICTURE): Ask mother to point to dark green or orange vegetables and fruits that her family commonly eats.

CHECKING QUESTIONS: •What vegetables have you been giving to [INFANT]?•What fruits have you been giving to [INFANT]?•How have you been preparing them for [INFANT]? (If yes PRAISE; if not, ENCOURAGE the mother to prepare vegetables and fruits for her baby) MOTIVATION: •[INFANT] will like food with fruits and vegetables in them and will stay healthier and become smarter

REMINDERS: •Before preparing food and feeding [INFANT], wash your hands with soap and water. Washing gets rid of germs that can make [INFANT] sick. At this age, children like to pick up food and feed themselves/ or put their fingers in their mouth. Wash their hands to avoid germs.
