RESUMEN
Stove stacking (concurrent use of multiple stoves and/or fuels) is a poorly quantified practice in regions where efforts to transition household energy to cleaner stoves/or fuels are on-going. Using biomass-burning stoves alongside clean stoves undermines health and environmental goals. This review synthesizes stove stacking data gathered from eleven case studies of clean cooking programs in low/middle-income country settings. Analyzed data are from ministry and program records, research studies, and informant interviews. Thematic analysis identify key drivers of stove stacking behavior in each setting. Significant (28%-100%) stacking with traditional cooking methods was observed in all cases. Reason for traditional fuel use includes: costs of clean fuel; mismatches between cooking technologies and household needs; and unreliable fuel supply. National household surveys often focus on 'primary' cookstoves and miss stove stacking data. Thus more attention should be paid to discontinuation of traditional stove use, not solely adoption of cleaner stoves/fuels. Future energy policies and programs should acknowledge the realities of stacking and incorporate strategies at the design stage to transition away from polluting stoves/fuels. Seven principles for clean cooking system program design and policy are presented, focused on a shift toward "cleaner stacking" that could yield household air pollution reductions approaching WHO targets.
RESUMEN
Globally, women's involvement in clean cooking value chains has been minimal. This is partly because of the multiple challenges faced by women that impede their capacity to effectively engage in the energy sector. To better discern gender-specific differences in involvement in the energy sector, the authors conducted a randomized trial in Kenya to compare sales performance of newly trained male and female improved cookstove entrepreneurs and to test the effects of an agency-based empowerment training on business activity. A total of 257 entrepreneurs completed either a 4-day entrepreneurial training (control) or a 4-day empowerment training (intervention) and were followed for nearly 8 months documenting business activity and sales. The empowerment training led to more than doubling of sales for both genders. In addition, participants in the intervention group were significantly more likely to demonstrate business commitment over time and nearly three times more likely to be higher sellers (relative risk = 2.7, 95% CI [1.4, 5.4]), controlling for gender and rural/urban locale. Women outsold men by a margin of nearly 3 to 1 and were more likely to continue to pursue leads despite limited sales. Nonactive participants (those selling 1 improved cookstove or less) were a larger percentage of the control group (72%) than the intervention group (50%), and more men were nonactive participants (65% of men) compared with women (56% of women).These data show that women can serve as active improved cookstove entrepreneurs in both urban and rural settings and that targeted agency-based empowerment training can significantly increase women's capacity to engage effectively within the improved cookstove value chain.

To examine the relationship between measures of mother's caretaking, practice and individual agency on acute diarrhea and respiratory tract infections (ARTIs) of Indonesian children. Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child <5 years of age was assessed with multivariate logistic regression adjusting for socioeconomic status, residence type, mother's age and education, family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children <2 years of age. Maternal caretaking, especially agency, is strongly associated with lower prevalence of diarrhea and ARTIs in younger children. Interventions specifically designed to promote maternal autonomy and decision-making may lead to improved child health.

Background. Tuberculosis (TB) remains a significant global public health problem with known gender-related (male versus female) disparities. We reviewed the qualitative evidence (written/spoken narrative) for gender-related differences limiting TB service access from symptom onset to treatment initiation. Methods. Following a systematic process, we searched 12 electronic databases, included qualitative studies that assessed gender differences in accessing TB diagnostic and treatment services, abstracted data, and assessed study validity. Using a modified "inductive coding" system, we synthesized emergent themes within defined barriers and delays limiting access at the individual and provider/system levels and examined gender-related differences. Results. Among 13,448 studies, 28 studies were included. All were conducted in developing countries and assessed individual-level barriers; 11 (39%) assessed provider/system-level barriers, 18 (64%) surveyed persons with suspected or diagnosed TB, and 7 (25%) exclusively surveyed randomly sampled community members or health care workers. Each barrier affected both genders but had gender-variable nature and impact reflecting sociodemographic themes. Women experienced financial and physical dependence, lower general literacy, and household stigma, whereas men faced work-related financial and physical barriers and community-based stigma. Conclusions. In developing countries, barriers limiting access to TB care have context-specific gender-related differences that can inform integrated interventions to optimize TB services.
RESUMEN
BACKGROUND: India has among the highest rates of infant malnutrition. Few studies investigating the growth patterns of HIV-exposed infants in India or the impact of timing of HIV infection on growth in settings such as India exist. METHODS: We used data from the Six Week Extended Nevirapine (SWEN) trial to compare the growth patterns of HIV-infected and HIV-exposed but uninfected infants accounting for timing of HIV infection, and to identify risk factors for stunting, underweight and wasting. Growth and timing of HIV infection were assessed at weeks 1, 2, 4, 6, 10, 14 weeks and 6, 9, 12 months of life. Random effects multivariable logistic regression method was used to assess factors associated with stunting, underweight and wasting. RESULTS: Among 737 HIV-exposed infants, 93 (13%) were HIV-infected by 12 months of age. Among HIV-infected and uninfected infants, baseline prevalence of stunting (48% vs. 46%), underweight (27% vs. 26%) and wasting (7% vs. 11%) was similar (p>0.29), but by 12 months stunting and underweight, but not wasting, were significantly higher in HIV-infected infants (80% vs. 56%, 52% vs. 29%, p< 0.0001; 5% vs. 6%, p=0.65, respectively). These differences rapidly manifested within 4-6 weeks of birth. Infants infected in utero had the worst growth outcomes during the follow-up period. SWEN was associated with non-significant reductions in stunting and underweight among HIV-infected infants and significantly less wasting in HIV-uninfected infants. In multivariate analysis, maternal CD4 < 250, infant HIV status, less breastfeeding, low birth weight, non-vaginal delivery, and infant gestational age were significant risk factors for underweight and stunting. CONCLUSION: Baseline stunting and underweight was high in both HIV-infected and uninfected infants; growth indices diverged early and were impacted by timing of infection and SWEN prophylaxis. Early growth monitoring of all HIV-exposed infants is an important low-cost strategy for improving health and survival outcomes of these infants. TRIAL REGISTRATION: NCT00061321.

OBJECTIVE: To examine the determinants of low birthweight (LBW), small-for-gestation (SGA) and preterm births in Lombok, Indonesia, an area of high infant mortality. METHODS: Data from The Supplementation with Multiple Micronutrient Intervention Trial (SUMMIT), a double-blind cluster-randomised controlled trial, were analysed. The odds ratio of factors known to be associated with LBW, SGA and preterm birth was assessed and adjusted for the cluster design of the trial using hierarchical logistic regression. Determinants included constitutional, demographic and psychosocial factors, toxic exposure, maternal nutrition and obstetric history and maternal morbidity during and prior to pregnancy. Population attributable risks of modifiable determinants were calculated. RESULTS: A cohort of 14,040 singleton births was available for analysis of LBW, with 13,498 observations for preterm births and 13,461 for SGA births. Determinants of LBW and SGA were similar and included infant's sex, woman's education, season at birth, mothers' residence, household wealth, maternal mid-upper arm circumference (MUAC), height and a composite variable of birth order and pregnancy interval. Socioeconomic indicators were also related to preterm births and included mother's education, residence and household wealth, while nutritional-related factors including low MUAC and birth order and interval were associated with preterm birth but not maternal height. Nausea was protective of preterm birth, while diarrhoea was associated with higher odds of preterm birth. Oedema during pregnancy was protective of SGA but associated with higher odds of preterm delivery. Around 33%, 13% and 13% of the determinants of LBW, SGA and preterm births were preventable. CONCLUSION: Women's education, maternal nutrition and household wealth and family planning are key factors to improving birth outcomes.

BACKGROUND: Clinical trials can serve as an opportunity gateway for enhanced health benefits to the target population, above and beyond the specific intervention being tested. OBJECTIVE: The Supplementation with Multiple Micronutrients Intervention Trial (SUMMIT), a randomized, controlled clinical trial in Lombok, Indonesia, found that supplementation during pregnancy with multiple micronutrients reduced 90-day infant mortality by nearly 20% as compared with iron-folic acid. This trial was designed as both a program and research trial and used community facilitators to serve as liaisons between the study and the pregnant women. This analysis documents the programmatic impacts of SUMMIT on health-seeking and early infant mortality resulting from community facilitators' field activities. METHODS: Data on compliance, human resource practices, health-seeking, and health outcomes from the 31,290 SUMMIT enrollees were analyzed. RESULTS: Overall compliance with either iron-folic acid or multiple micronutrients was high in the program, at 85.0%. Early prenatal care visits increased significantly. Sixty-three percent of primiparous women used a skilled birth attendant (SBA); among multiparous women, the rate of use of a SBA rose from 35% for the last birth to 53%. Use of a SBA resulted in a 30% reduction in early infant mortality (RR, 0.70; 95% CI, 0.59 to 0.83; p < .0001), independently of any reductions due to multiple micronutrients. The community facilitators played a central role in improving health-seeking; however, the quality of the community facilitators' performance was associated with the impact of the micronutrient supplement on infant health. In a subsample of community facilitators, better-performing facilitators were found to markedly improve the overall impact of the multiple micronutrients on early infant mortality (RR, 0.67; 95% CI, 0.49 to 0.92; p = .0117). In contrast, infants of women with poorly performing community facilitators were found to derive no additional benefit from the multiple micronutrients (RR, 1.04; 95% CI, 0.64 to 1.72; p = .8568). CONCLUSIONS: Systematic enhancements to the quality of implementation of SUMMIT led to significant increases in use of SBAs at delivery, resulting in a 30% reduction in early infant mortality independent of the impact of micronutrient supplementation. Therefore, if women were to consume multiple micronutrients on a regular basis and were to use a SBA at delivery, the risk of early infant mortality could be reduced by nearly 50%. The impacts of community facilitators in effecting changes in women's health behaviors are notable and are applicable to other health programs. Enhancements to program implementation should be driven by evidence, be accountable to the communities the program serves, and be evaluated on the basis of measurable gains in health for women and children.

HIV-positive women of reproductive age face challenges in decision making related to pregnancy. Understanding factors influencing repeat pregnancies in women with known HIV status are necessary to guide interventions and counseling strategies to better inform and support them. We compared three groups of women attending a large antenatal clinic in Pune, India. They include: Group A--63 HIV-positive women coming for care for a repeat pregnancy after being diagnosed in a previous pregnancy; Group B--64 HIV-negative (repeat) pregnant women attending this antenatal clinic; and Group C--63 HIV-positive non-pregnant women currently enrolled in an ongoing clinical trial. Comparisons of Group A and B indicate that the likelihood of unplanned repeat pregnancies was significantly higher in HIV-positive (70%) than HIV-negative (36%) women (OR=4.1, CI: 2.0-8.7). Inability to terminate the pregnancy (31%) and familial obligations (40%) appear to be important for continuing the unplanned repeat pregnancy. Despite high reported contraceptive use by HIV-positive women, pregnancies still occurred. Death of their youngest child is an important factor as 21% of HIV-positive pregnant women lost their youngest child compared with 3% of HIV-negative women and 3% of HIV-positive non-pregnant women (p<0.001). Repeat pregnancies were more likely to occur for women who did not disclose their HIV status to their spouse. Thus the majority of the repeat pregnancies for HIV-positive women were both unplanned and unwanted.

Few health care facilities are adequately prepared to manage and care for HIV/AIDS patients in India. Nurses play a critical role in patient care but are often ill-equipped to deal with their own fears of occupational risk and handle the clinical aspects of HIV/AIDS care, leading to stigma and discrimination toward HIV-positive patients. The authors examine the impact of a 4-day HIV/AIDS health education program on knowledge and attitudes of nurses in a government hospital. This education program was developed using a training of trainers model and qualitative research. A total of 21 master trainers underwent 6 days of training and began training of 552 hospital nurses (in 2004-2005). Using a pretest-posttest design, the authors assessed changes in knowledge and attitudes of 371 trained nurses. Significant improvements were seen in nurses' HIV/AIDS knowledge in all areas including care, treatment, and issues of confidentiality and consent. Fear of interaction with people living with HIV/AIDS was reduced significantly. The short course was successful in increasing nurses' knowledge in all aspects. There is great potential to expand this stigma-reduction intervention to other public and private hospitals.

In 2003, India had over 5.1 million infected individuals living with HIV/AIDS. The percentage of all HIV cases attributed to perinatal transmission has been increasing steadily from 0.33% of total cases in 1999 to 2.80% in 2004. Recent statistics indicate that over 130,000 infants have been infected through this route. Despite recent advances in reducing in utero and interpartum transmission with the use of antiretrovirals, there is a critical need to make infant feeding safer. Current UNAIDS/WHO/UNICEF recommendations stress avoidance of all breast-feeding if replacement feeding fulfills the key requirements of being affordable, feasible, acceptable, sustainable, and safe. In this paper, we examine how the UNAIDS/WHO/UNICEF recommendations have been actualized within the context of an urban government hospital in India. The documented patterns of infant feeding by HIV-positive mothers in Pune, India, from 2000 to 2004, highlight the complexities of making an informed and healthy choice under suboptimal conditions. The data indicate that interpersonal variations in the key requirements greatly influence the optimal practice to minimize mortality risks. Moreover, local information on health outcomes is crucial to tailoring policy recommendations to save lives. We propose the development of a decision-making algorithm that includes factors affecting mother-to-infant transmission, including site-specific data on health risks to the mother and the child. Such an algorithm would allow identification of the healthiest feeding choice and would minimize the pitfalls of promoting homogeneous practices lacking site-specific evidence-based evaluation.

Access to safe breast-feeding alternatives for HIV-infected mothers and their infants in many settings is limited. We compared the rates of early postpartum hospitalization of infants born to HIV-infected mothers using different infant-feeding practices in a large government hospital in Pune, India. From March 1, 2000 to November 30, 2001, infants born to HIV-infected mothers were followed in a postpartum clinic. All mothers had received a standard short course of antenatal zidovudine. Infant-feeding practices were assessed within 3 d of delivery, prior to postpartum hospital discharge. Sixty-two of 148 mothers (42%) were breast-feeding their infants. Eighty-six of the mothers (58%) were providing replacement feeding, primarily diluted cow, goat or buffalo milk (top feeding). Twenty-one of the 148 participating infants (14.2%) born during the study period required hospitalization within the 1st 6 mo of life and 6 infants required repeat hospitalization. All hospitalized infants were receiving replacement feeding with a rate of 0.093 hospitalizations per 100 person-days (95% CI, 0.062 to 0.136). The reasons for hospitalization included acute gastroenteritis (48.1%), pneumonia (18.5%), septicemia (11.1%) and jaundice (11.1%). A high risk for early postpartum hospitalization was seen in replacement-fed infants born to HIV-infected mothers in Pune, India. In settings such as India, where access to safe replacement feeding is limited, interventions making exclusive breast-feeding safer for HIV-infected mothers and infants are needed. Such interventions would be valuable additions to the very effective national prevention programs that currently rely on the provision of short-course zidovudine and nevirapine.

Exclusive breast-feeding is widely accepted and advocated in India; however, clinicians are now faced with advising women infected with human immunodeficiency virus (HIV) about the risks and benefits of other infant feeding options. This study assessed factors that influence the infant feeding decisions of HIV-infected mothers in Pune, India. From December 2000 to April 2002, HIV-positive (HIV(+)) pregnant women (n = 101) from a government hospital antenatal clinic were interviewed prepartum about infant feeding intention, feeding practice immediately postpartum and feeding after a minimum of 2 wk postpartum. Of the HIV(+) sample, the last 39 were interviewed more intensively to examine factors affecting feeding decision making. We found that an equal number of HIV(+) women intended to breast-feed (44%) or give top milk (44%) (diluted animal milk). Women who chose to top feed were also more likely to disclose their HIV status to family members. Mixed feeding occurred frequently in our sample (29%); however, for the majority of those (74%), it lasted only 3 d postpartum. The hospital counselor had an important role in assisting women in their intended feeding choice as well as actual practice. The time immediately after delivery was noted as critical for recounseling about infant feeding and further support of the woman's decision, thus lowering the risk of mixed feeding. Lack of funds, poor hygienic conditions and risk of social repercussions were more commonly noted as reasons to breast-feed. Top milk, the alternative for breast-milk used in this population, however, must be investigated further to assess its nutritional value and safety before it can be endorsed widely for infants of HIV(+) women.
