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

Aim. To evaluate the effect of breastfeeding on long-term (breast carcinoma, ovarian carcinoma, osteoporosis and type 2 diabetes mellitus) and short-term (lactational amenorrhoea, postpartum depression, postpartum weight change) maternal health outcomes. Methods. A systematic literature search was conducted in PubMed, Cochrane Library and CABI databases. Outcome estimates of odds ratios or relative risks or standardised mean differences were pooled. In cases of heterogeneity, subgroup analysis and meta-regression were explored. Results. Breastfeeding >12 months was associated with reduced risk of breast and ovarian carcinoma by 26% and 37%, respectively. No conclusive evidence of an association between breastfeeding and bone mineral density was found. Breastfeeding was associated with 32% lower risk of type 2 diabetes. Exclusive breastfeeding and predominant breastfeeding were associated with longer duration of amenorrhoea. Shorter duration of breastfeeding was associated with higher risk of postpartum depression. Evidence suggesting an association of breastfeeding with postpartum weight change was lacking. Conclusion. This review supports the hypothesis that breastfeeding is protective against breast and ovarian carcinoma, and exclusive breastfeeding and predominant breastfeeding increase the duration of lactational amenorrhoea. There is evidence that breastfeeding reduces the risk of type 2 diabetes. However, an association between breastfeeding and bone mineral density or maternal depression or postpartum weight change was not evident

Interventions to improve breastfeeding outcomes: A systematic review and meta-analysis

Aim. To provide comprehensive evidence of the effect of interventions on early initiation, exclusive, continued and any breastfeeding rates when delivered in five settings: (i) Health systems and services (ii) Home and family environment (iii) Community environment (iv) Work environment (v) Policy environment or a combination of any of above. Methods. Of 23977 titles identified through a systematic literature search in PUBMED, Cochrane and CABI, 195 articles relevant to our objective, were included. We reported the pooled relative risk and corresponding 95% confidence intervals as our outcome estimate. In cases of high heterogeneity, we explored its causes by subgroup analysis and meta-regression and applied random effects model. Results. Intervention delivery in combination of settings seemed to have higher improvements in breastfeeding rates. Greatest improvements in early initiation of breastfeeding, exclusive breastfeeding and continued breastfeeding rates, were seen when counselling or education were provided concurrently in home and community, health systems and community, health systems and home settings, respectively. Baby friendly hospital support at health system was the most effective intervention to improve rates of any breastfeeding. Conclusion. To promote breastfeeding, interventions should be delivered in a combination of settings by involving health systems, home and family and the community environment concurrently

Early iron supplementation in very low birth weight infants–a randomized controlled trial

Aim: To evaluate if supplementing iron at 2 weeks of age improves serum ferritin and/or haematological parameters at 2 months of life in very low birth weight (VLBW) infants. Methods: Preterm VLBW infants who received at least 100 mL/kg/day of oral feeds by day 14 of life were randomized to either ‘early iron’ (3–4 mg/kg/day orally from 2 weeks) or ‘control’ (no iron until 60 days) groups. Infants were followed up fortnightly and all morbidities were prospectively recorded. Serum ferritin was measured at 60 days by enzyme immunoassay method. Results: Forty-six infants were included in the study; primary outcome was available for 42 infants. There was no difference in either serum ferritin (mean: 50.8 vs. 45.3 μg/L; adjusted difference in means: 5.8, 95% CI: −3.0, 14.6; p = 0.19) or haematocrit (32.5 ± 5.3 vs. 30.8 ± 6.3%; p = 0.35) at 60 days between the early iron and control groups. The magnitude of fall in serum ferritin from baseline to the end of study period was also not different between the groups (4.9 vs. 13.8 μg/L; difference in means: 8.8; 95% CI: −0.3, 17.9; p = 0.06). The requirement of blood transfusions (9.5 vs. 13%; p = 0.63) and a composite outcome of common neonatal morbidities (19% vs. 21.7%; p = 0.55) were also not different between the two groups. Conclusion: Supplementing iron at 2 weeks of age in preterm VLBW infants did not improve either serum ferritin or the haematological parameters at 2 months when compared to the standard practice of starting iron from 8 weeks of age

Evaluation of phototherapy devices used for neonatal Hyperbilirubinemia

Objective: To compare phototherapy devices based on their physical and photo-biological characteristics viz spectral properties, maximum and mean irradiance, treatable percentage of body surface area, decay of irradiance over time and in vitro photoisomerisation of bilirubin. Design: In vitro experimental study. Setting: Ocular pharmacy laboratory at a tertiary care hospital. Methodology: All the characteristics were measured at a fixed distance of 35 cm from one compact fluorescent lamp (CFL) and three light emitting diode (LED) phototherapy devices in a dark room with an irradiance of < 0.1μW/cm2/nm. Estimation of products of in vitro photoisomerisation was done using liquid chromatography — tandem mass spectroscopy (LC-MS/MS). Results: The emission spectral data were comparable between the phototherapy devices. The devices, however, differed in their maximum irradiance with the spot and indigenous LED units having the highest and lowest values, respectively (56.5 and 16.8μW/cm2/nm). The mean irradiance — measured in 5x5cm grids falling within the silhouette of a term baby — of the spot and improvised LED devices were low (26.8μW/cm2/nm and 11.5μW/cm2/ nm, respectively) possibly due to unevenness in the irradiance of light falling within the silhouette. There was a significant difference in the amount of bilirubin left after exposure to light over a 2-hour time period (% reduction of bilirubin) among the four devices (P=0.001); at 120 minutes after exposure, the amount of bilirubin left was lowest for the CFL (16%) and spot LED (17%) devices and highest for the indigenous LED unit (41%). Conclusions: The four phototherapy devices differed markedly in their physical and photobiological characteristics. Since the efficacy of a device is dependent not only on the maximum irradiance but also on the mean irradiance, rate of decay of irradiance, and treatable surface area of the foot print of light, each phototherapy device should have these parameters verified and confirmed before being launched for widespread use

Breastfeeding 1 Breastfeeding in the 21st century: epidemiology, mechanisms, and lifelong eff ect

The importance of breastfeeding in low-income and middle-income countries is well recognised, but less consensus exists about its importance in high-income countries. In low-income and middle-income countries, only 37% of children younger than 6 months of age are exclusively breastfed. With few exceptions, breastfeeding duration is shorter in high-income countries than in those that are resource-poor. Our meta-analyses indicate protection against child infections and malocclusion, increases in intelligence, and probable reductions in overweight and diabetes. We did not fi nd associations with allergic disorders such as asthma or with blood pressure or cholesterol, and we noted an increase in tooth decay with longer periods of breastfeeding. For nursing women, breastfeeding gave protection against breast cancer and it improved birth spacing, and it might also protect against ovarian cancer and type 2 diabetes. The scaling up of breastfeeding to a near universal level could prevent 823 000 annual deaths in children younger than 5 years and 20 000 annual deaths from breast cancer. Recent epidemiological and biological fi ndings from during the past decade expand on the known benefi ts of breastfeeding for women and children, whether they are rich or poor

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

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 people's movement
