  • Silent losses

    Open AccessJames P Wirth, Amirhossein Yarparvar et al.ARTICLEBMJ Global Health2025

    BACKGROUND: Significant physiological changes occur in adolescence, including the onset of menarche in girls. However, the extent to which menstrual bleeding contributes to anaemia and micronutrient deficiencies remains unclear. This study assesses the prevalence of anaemia and micronutrient deficiencies and examines their association with menarcheal status, menstrual bleeding severity and other factors among adolescent girls in Lebanon. METHODS:…

  • The impact of poverty on child malnutrition and health in Lebanon

    Open AccessNicolai Petry, Omar Obeid et al.ARTICLEInternational Journal for Equity…2025

    Our findings underscore the profound impact of poverty on child malnutrition and infections. To effectively and sustainably address these challenges, a holistic, multisectoral approach is needed, combining targeted nutritional programs, social protection programs, WASH initiatives and educational interventions to break the cycle of poverty and malnutrition

  • The global burden of high fasting plasma glucose associated with zinc deficiency

    Open AccessJames P Wirth, Wu Zeng et al.ARTICLEPLOS Global Public Health2023

    Non-communicable diseases (NCDs) account for the largest share of the global disease burden, and increasing evidence shows that zinc deficiency (ZD) contributes to NCDs by inducing oxidative stress, insulin resistance, and impaired lipid metabolism. A systematic review and meta-analysis was conducted to determine whether ZD was associated with fasting plasma glucose (FPG), a key risk factor for NCDs. A random effects meta-analysis was conducted t…

  • Micronutrient deficiencies among preschool-aged children and women of reproductive age worldwide

    Open AccessG A Stevens, Ty Beal et al.ARTICLEThe Lancet Global Health2022

    BACKGROUND: Micronutrient deficiencies compromise immune systems, hinder child growth and development, and affect human potential worldwide. Yet, to our knowledge, the only existing estimate of the global prevalence of micronutrient deficiencies is from over 30 years ago and is based only on the prevalence of anaemia. We aimed to estimate the global and regional prevalence of deficiency in at least one of three micronutrients among preschool-aged…

  • Risk factors of stunting and wasting in Somali pre-school age children

    Open AccessWilliam Donkor, William E S Donkor et al.ARTICLEBMC Public Health2022

    Nutritional status of children in Somalia may be improved by prevention of diarrhea and other infections and improvements in household food security

  • Risk factors of anaemia and iron deficiency in Somali children and women

    Open AccessJames P Wirth, Fatmata Sesay et al.ARTICLEMaternal and Child Nutrition2021

    There are limited data on the prevalence of anaemia and iron deficiency (ID) in Somalia. To address this data gap, Somalia's 2019 micronutrient survey assessed the prevalence of anaemia and ID in children (6-59 months) and non-pregnant women of reproductive age (15-49 years). The survey also collected data on vitamin A deficiency, inflammation, malaria and other potential risk factors for anaemia and ID. Multivariable Poisson regressions models w…

  • Risk factors for anaemia among Ghanaian women and children vary by population group and climate zone

    Open AccessNicolai Petry, James P Wirth et al.ARTICLEMaternal and Child Nutrition2020

    Anaemia has serious effects on human health and has multifactorial aetiologies. This study aimed to determine putative risk factors for anaemia in children 6-59 months and 15- to 49-year-old non-pregnant women living in Ghana. Data from a nationally representative cross-sectional survey were analysed for associations between anaemia and various anaemia risk factors. National and stratum-specific multivariable regressions were constructed separate…

  • The Proportion of Anemia Associated with Iron Deficiency in Low, Medium, and High Human Development Index Countries

    Open AccessNicolai Petry, Ibironke Olofin et al.ARTICLENutrients2016

    Iron deficiency is commonly assumed to cause half of all cases of anemias, with hereditary blood disorders and infections such as hookworm and malaria being the other major causes. In countries ranked as low, medium, and high by the Human Development Index, we conducted a systematic review of nationally representative surveys that reported the prevalence of iron deficiency, iron deficiency anemia, and anemia among pre-school children and non-preg…

  • Assessment of the WHO Stunting Framework using Ethiopia as a case study

    Open AccessJames P Wirth, Fabian Rohner et al.ARTICLEMaternal and Child Nutrition2016

    Poor linear growth in children <5 years old, or stunting, is a serious public health problem particularly in Sub-Saharan Africa. In 2013, the World Health Organization (WHO) released a conceptual framework on the Context, Causes and Consequences of Childhood Stunting (the 'WHO framework') that identifies specific and general factors associated with stunting. The framework is based upon a global review of data, and we have applied it to a country-…
