Abstract

Food insecurity and energy insecurity are critical global health issues, with implications for dietary diversity and infant feeding practices. This study evaluated the effects of an intervention for a liquefied petroleum gas (LPG) cook-stove and for free fuel on food security and dietary diversity among women and infants in four diverse settings. The Household Air Pollution Intervention Network (HAPIN) study is a randomized controlled trial that enrolled 800 pregnant women each in Guatemala, Peru, India, and Rwanda. Participants (N = 3195) were randomly assigned to intervention or control groups, with intervention households receiving an LPG cook-stove and free fuel for 18 months. We measured household food insecurity using the Food Insecurity Experience Scale and dietary diversity for women and infants using the Minimum Dietary Diversity – Women and WHO infant and young child feeding questionnaires, respectively. We conducted an intention-to-treat analysis to evaluate the effect of the intervention on each outcome. At baseline, 27.4% of households were mildly food insecure, 15.6% were moderately or severely food insecure, and 26.8% of women achieved minimum dietary diversity. At end-line, the intervention significantly reduced moderate or severe food insecurity (RR: 0.75, 95% CI: 0.58–0.97) and improved dietary diversity among our analytic sample of 2868 women (RR: 1.16, 95% CI: 1.01–1.33) and 2836 infants aged 12 months (RR: 1.07, 95% CI: 1.002–1.15). Our findings suggest that interventions that increase energy security can be nutrition-sensitive and contribute to improved food and nutrition security.

免费燃料液化石油气炉灶干预对妇女和婴儿粮食不安全和饮食多样性的影响：多国随机对照试验

粮食不安全和能源不安全是严重的全球健康问题，影响到饮食多样性和婴儿喂养做法。本研究评估了液化石油气炉灶和免费燃料干预在四种不同环境下对妇女和婴儿粮食安全和饮食多样性的影响。家庭空气污染干预网络（HAPIN）研究是一项随机对照试验，在危地马拉、秘鲁、印度和卢旺达各招募了800名孕妇。参与者（N = 3195）被随机分配到干预组或对照组，干预家庭获得液化石油气炉灶和免费燃料18个月。我们分别使用《粮食不安全体验量表》衡量家庭粮食不安全状况，使用《最低膳食多样性-妇女》和《世卫组织婴幼儿喂养问卷》衡量妇女和婴儿的饮食多样性。我们进行了意向治疗分析，以评估干预对每个结果的影响。在基线时，27.4%的家庭处于轻度粮食不安全状态，15.6%的家庭处于中度或严重粮食不安全状态，26.8%的妇女达到了最低限度的饮食多样性。在终点，干预显著减少了中度或重度食物不安全（RR: 0.75, 95% CI: 0.58-0.97），并改善了2868名女性（RR: 1.16, 95% CI: 1.01-1.33）和2836名12个月婴儿（RR: 1.07, 95% CI: 1.002-1.15）的饮食多样性。我们的研究结果表明，提高能源安全的干预措施可能对营养敏感，有助于改善粮食和营养安全。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
