Zinc Supplementation in Young Children with Acute Diarrhea in India

BACKGROUND In developing countries the duration and severity of diarrheal illnesses are greatest among infants and young children with malnutrition and impaired immune status, both factors that may be associated with zinc deficiency. In children with severe zinc deficiency, diarrhea is common and responds quickly to zinc supplementation. METHODS To evaluate the effects of daily supplementation with 20 mg of elemental zinc on the duration and severity of acute diarrhea, we conducted a double-blind, randomized, controlled trial involving 937 children, 6 to 35 months of age, in New Delhi, India. All the children also received oral rehydration therapy and vitamin supplements. RESULTS Among the children who received zinc supplementation, there was a 23 percent reduction (95 percent confidence interval, 12 percent to 32 percent) in the risk of continued diarrhea. Estimates of the likelihood of recovery according to the day of zinc supplementation revealed a reduction of 7 percent (95 percent confidence interval, -9 percent to +22 percent) in the risk of continued diarrhea during days 1 through 3 and a reduction of 38 percent (95 percent confidence interval, 27 percent to 48 percent) after day 3. When zinc supplementation was initiated within three days of the onset of diarrhea, there was a 39 percent reduction (95 percent confidence interval, 7 percent to 61 percent) in the proportion of episodes lasting more than seven days. In the zinc-supplementation group there was a decrease of 39 percent (95 percent confidence interval, 6 percent to 70 percent) in the mean number of watery stools per day (P = 0.02) and a decrease of 21 percent (95 percent confidence interval, 10 percent to 31 percent) in the number of days with watery diarrhea. The reductions in the duration and severity of diarrhea were greater in children with stunted growth than in those with normal growth. CONCLUSION For infants and young children with acute diarrhea, zinc supplementation results in clinically important reductions in the duration and severity of diarrhea.

Why invest, and what it will take to improve breastfeeding practices?

Despite its established benefits, breastfeeding is no longer a norm in many communities. Multifactorial determinants of breastfeeding need supportive measures at many levels, from legal and policy directives to social attitudes and values, womens work and employment conditions, and health-care services to enable women to breastfeed. When relevant interventions are delivered adequately, breastfeeding practices are responsive and can improve rapidly. The best outcomes are achieved when interventions are implemented concurrently through several channels.

Reproductive health, and child health and nutrition in India: meeting the challenge

OBJECTIVE To determine the association of different feeding patterns for infants (exclusive breastfeeding, predominant breastfeeding, partial breastfeeding and no breastfeeding) with mortality and hospital admissions during the first half of infancy. METHODS This paper is based on a secondary analysis of data from a multicentre randomized controlled trial on immunization-linked vitamin A supplementation. Altogether, 9424 infants and their mothers (2919 in Ghana, 4000 in India and 2505 in Peru) were enrolled when infants were 18-42 days old in two urban slums in New Delhi, India, a periurban shanty town in Lima, Peru, and 37 villages in the Kintampo district of Ghana. Mother-infant pairs were visited at home every 4 weeks from the time the infant received the first dose of oral polio vaccine and diphtheria-pertussis-tetanus at the age of 6 weeks in Ghana and India and at the age of 10 weeks in Peru. At each visit, mothers were queried about what they had offered their infant to eat or drink during the past week. Information was also collected on hospital admissions and deaths occurring between the ages of 6 weeks and 6 months. The main outcome measures were all-cause mortality, diarrhoea-specific mortality, mortality caused by acute lower respiratory infections, and hospital admissions. FINDINGS There was no significant difference in the risk of death between children who were exclusively breastfed and those who were predominantly breastfed (adjusted hazard ratio (HR) = 1.46; 95% confidence interval (CI) = 0.75-2.86). Non-breastfed infants had a higher risk of dying when compared with those who had been predominantly breastfed (HR = 10.5; 95% CI = 5.0-22.0; P < 0.001) as did partially breastfed infants (HR = 2.46; 95% CI = 1.44-4.18; P = 0.001). CONCLUSION There are two major implications of these findings. First, the extremely high risks of infant mortality associated with not being breastfed need to be taken into account when informing HIV-infected mothers about options for feeding their infants. Second, our finding that the risks of death are similar for infants who are predominantly breastfed and those who are exclusively breastfed suggests that in settings where rates of predominant breastfeeding are already high, promotion efforts should focus on sustaining these high rates rather than on attempting to achieve a shift from predominant breastfeeding to exclusive breastfeeding.

Breastfeeding and maternal health outcomes: a systematic review and meta-analysis

BACKGROUND Exclusive breastfeeding is recommended until age 6 months. We assessed the feasibility, effectiveness, and safety of an educational intervention to promote exclusive breastfeeding for this length of time in India. METHODS We developed the intervention through formative research, pair-matched eight communities on their baseline characteristics, and randomised one of each pair to receive the intervention and the other to no specific intervention. We trained health and nutrition workers in the intervention communities to counsel mothers for exclusive breastfeeding at multiple opportunities. We enrolled 1115 infants born in the 9 months after training-552 in the intervention and 473 in the control communities. Feeding at age 3 months, and anthropometry and of diarrhoea prevalence at age 3 months and 6 months were assessed. All analyses were by intention to treat. FINDINGS We assessed 483 and 412 individuals at 3 months in the intervention and control groups, respectively, and 468 and 412 at 6 months. At 3 months, exclusive breastfeeding rates were 79% (381) in the intervention and 48% (197) in the control communities (odds ratio 4.02, 95% CI 3.01-5.38, p<0.0001). The 7-day diarrhoea prevalence was lower in the intervention than in the control communities at 3 months (0.64, 0.44-0.95, p=0.028) and 6 months (0.85, 0.72-0.99, p=0.04). The mean weights and lengths, and the proportion with weight-for-height or height-for-age Z scores of 2 or less, at age 3 months and 6 months did not differ much between groups. Intervention effect on exclusive breastfeeding, diarrhoeal morbidity, and anthropometry at age 6 months in the low-birthweight subgroup was similar to that for all births. INTERPRETATION Promotion of exclusive breastfeeding until age 6 months in a developing country through existing primary health-care services is feasible, reduces the risk of diarrhoea, and does not lead to growth faltering.

Optimal breastfeeding practices and infant and child mortality: a systematic review and meta-analysis.

India, with a population of more than 1 billion people, has many challenges in improving the health and nutrition of its citizens. Steady declines have been noted in fertility, maternal, infant and child mortalities, and the prevalence of severe manifestations of nutritional deficiencies, but the pace has been slow and falls short of national and Millennium Development Goal targets. The likely explanations include social inequities, disparities in health systems between and within states, and consequences of urbanisation and demographic transition. In 2005, India embarked on the National Rural Health Mission, an extraordinary effort to strengthen the health systems. However, coverage of priority interventions remains insufficient, and the content and quality of existing interventions are suboptimum. Substantial unmet need for contraception remains, adolescent pregnancies are common, and access to safe abortion is inadequate. Increases in the numbers of deliveries in institutions have not been matched by improvements in the quality of intrapartum and neonatal care. Infants and young children do not get the health care they need; access to effective treatment for neonatal illness, diarrhoea, and pneumonia shows little improvement; and the coverage of nutrition programmes is inadequate. Absence of well functioning health systems is indicated by the inadequacies related to planning, financing, human resources, infrastructure, supply systems, governance, information, and monitoring. We provide a case for transformation of health systems through effective stewardship, decentralised planning in districts, a reasoned approach to financing that affects demand for health care, a campaign to create awareness and change health and nutrition behaviour, and revision of programmes for child nutrition on the basis of evidence. This agenda needs political commitment of the highest order and the development of a peoples movement.

Growth performance of affluent Indian children is similar to that in developed countries

The association between low initial plasma zinc concentration and risk of morbidity over the subsequent 3 mo was examined in a cohort of 116 children aged 12-59 mo recovering from acute diarrhea. Children with low initial plasma zinc (< or = 8.4 micromol/L) had more episodes of diarrhea [risk ratio (RR): 1.47; 95% CI: 1.03, 2.49) and severe diarrhea, defined as passage of > or = 5 liquid stools in a 24-h period, (RR: 1.70; 95% CI: 1.06, 2.72) than did children with normal plasma zinc (> 8.4 micromol/L). The mean prevalence rate of diarrhea associated with fever was 4 times higher in the zinc-deficient group (P = 0.01). Overall, the difference in the number of episodes of acute lower respiratory tract infections (ALRIs) between the two groups was not statistically significant (RR: 1.76; 95% CI: 0.88-3.53) but the mean prevalence rate of ALRIs was 3.5 times higher in children with low plasma zinc (P = 0.05). The increased risk of diarrhea and ALRIs episodes in zinc-deficient children was larger in boys than in girls. These results show that children with low plasma zinc concentrations are at risk for increased diarrheal and respiratory morbidity.
