Reducing micronutrient deficiencies in Pakistani children
Objective To estimate the cost-effectiveness of price subsidies on fortified packaged complementary foods (FPCF) in reducing iodine deficiency, iron-deficiency anaemia and vitamin A deficiency in Pakistani children. Design The study proceeded in three steps: (i) we determined the current lifetime costs of the three micronutrient deficiencies with a health economic model; (ii) we assessed the price sensitivity of demand for FPCF with a market surv…
Effectiveness of zinc-fortified water on zinc intake, status and morbidity in Kenyan pre-school children
Objective Zn deficiency and diarrhoea are prevalent and may coexist in children living in low-resource settings. Recently, a novel approach for delivering Zn via microbiologically treated, Zn-fortified water was shown to be effective in improving Zn status in West African schoolchildren. We assessed the effectiveness of Zn-fortified, microbiologically purified water delivered as a household intervention on Zn intake, status and morbidity in child…
Urinary iodine concentration identifies pregnant women as iodine deficient yet school-aged children as iodine sufficient in rural Niger
Objective To assess iodine status among pregnant women in rural Zinder, Niger and to compare their status with the iodine status of school-aged children from the same households. Design Seventy-three villages in the catchment area of sixteen health centres were randomly selected to participate in the cross-sectional survey. Setting Salt iodization is mandatory in Niger, requiring 20–60 ppm iodine at the retail level. Subjects A spot urine sample …
More than two-thirds of dietary iodine in children in northern Ghana is obtained from bouillon cubes containing iodized salt
Objective Bouillon cubes are widely consumed by poor households in sub-Saharan Africa. Because their main ingredient is salt, bouillon cubes could be a good source of iodine if iodized salt is used in their production and if their consumption by target groups is high. Our objective was to measure the iodine content of bouillon cubes, estimate their daily intake in school-aged children and evaluate their potential contribution to iodine intakes. D…
The iodized salt programme in Bangalore, India provides adequate iodine intakes in pregnant women and more-than-adequate iodine intakes in their children
Objective To compare the iodine status of pregnant women and their children who were sharing all meals in Bangalore, India. Design A cross-sectional study evaluating demographic characteristics, household salt iodine concentration and salt usage patterns, urinary iodine concentrations (UIC) in women and children, and maternal thyroid volume (ultrasound). Setting Antenatal clinic of an urban tertiary-care hospital, which serves a low-income popula…
In‐home fortification with 2.5 mg iron as NaFeEdta does not reduce anaemia but increases weight gain
In-home fortification of infants with micronutrient powders (MNPs) containing 12.5 mg iron may increase morbidity from infections; therefore, an efficacious low-dose iron-containing MNP might be advantageous. Effects of iron-containing MNPs on infant growth are unclear. We assessed the efficacy of a low-iron MNP on iron status and growth and monitored safety in a randomised, controlled, double-blind 1-year trial in 6-month-old infants (n = 287) c…
Prevalence and public health relevance of micronutrient deficiencies and undernutrition in pre-school children and women of reproductive age in Côte d'Ivoire, West Africa
Objective To provide nationally representative data on the prevalence of anaemia, vitamin A and Fe deficiencies among pre-school age children (pre-SAC) and non-pregnant women of reproductive age (WRA), and on vitamin B 12 and folate deficiencies in WRA, and the influence of inflammation on their interpretation. Design A cross-sectional survey to measure anthropometry, malaria parasitaemia and micronutrient status. Specifically, blood samples were…
Overweight increases risk of first trimester hypothyroxinaemia in iodine‐deficient pregnant women
Hypothyroxinaemia early in pregnancy may impair fetal brain development. Increased body weight has been associated with low thyroxine concentrations in non-pregnant women. In pregnant women, morbid maternal obesity is a risk factor for thyroid dysfunction. But whether lesser degrees of overweight that are much more common could be a risk factor for hypothyroxinaemia in pregnancy is unclear. The objective of this study was to investigate if overwe…
Need for coordinated programs to improve global health by optimizing salt and iodine intake
High dietary salt is a major cause of increased blood pressure, the leading risk for death worldwide. The World Health Organization (WHO) has recommended that salt intake be less than 5 g/day, a goal that only a small proportion of people achieve. Iodine deficiency can cause cognitive and motor impairment and, if severe, hypothyroidism with serious mental and growth retardation. More than 2 billion people worldwide are at risk of iodine deficienc…
Schoolchildren in the Principality of Liechtenstein are mildly iodine deficient
Objective To investigate the iodine status of schoolchildren in the Principality of Liechtenstein. Design A representative, cross-sectional principality-wide screening of iodine level in household salt and urinary iodine concentrations (UIC) in primary-school children. Data were compared with the WHO criteria and with 2009 iodine survey data from Switzerland, a neighbouring country that supplies most of the salt used in Liechtenstein. Settings Pr…
Decrease in the prevalence of paediatric adiposity in Switzerland from 2002 to 2007
Objective A national study in Switzerland in 2002 suggested nearly one in five schoolchildren was overweight. Since then, many programmes have been introduced in an attempt to control the problem. The aim of the present study was to determine the prevalence of childhood overweight in Switzerland five years later. Design In both studies a cross-sectional, three-stage, probability-proportional-to-size cluster sampling of schools throughout Switzerl…
The impact of iodised salt or iodine supplements on iodine status during pregnancy, lactation and infancy
Objectives: Monitoring of iodine status during pregnancy, lactation and infancy is difficult as there are no established reference criteria for urinary iodine concentration (UI) for these groups; so it is uncertain whether iodized salt programs meet the needs of these life stages. Design and Subjects: The method used in this paper was: 1) to estimate the median UI concentration that reflects adequate iodine intake during these life stages; and 2)…
