Free sugar intakes are currently higher than recommended for health, yet effective strategies for reducing consumption are yet to be elucidated. This work investigated the effects of different dietary recommendations for reducing free sugar (FS) intakes, on relevant outcomes, in UK adults consuming > 5 % of total energy intake (TEI) from FS. Using a randomised controlled parallel-group design, 242 adults received nutrient-based (n 61), nutrient- and food-based (n 60), nutrient-, food- and food-substitution-based (n 63) or no (n 58) recommendations for reducing FS at a single timepoint, with effects assessed for the following 12 weeks. Primary outcomes were FS intakes as a percentage of TEI (%FS) and adherence to the recommendations at week 12. Secondary outcomes included TEI, diet composition, sugar-rich and low-calorie-sweetened food consumption and anthropometry. In intention-to-treat analyses adjusted for baseline measures, %FS reduced in intervention groups (%FSchange = –2·5 to −3·3 %) compared with control (%FSchange = –1·2 %) (smallest B = –0·573, P = 0·03), with effects from week 1 until week 12 and no differences between interventions (largest B = 0·352, P = 0·42). No effects of the interventions were found in dietary profiles, but change in %FS was associated with change in %TEI from non-sugar carbohydrate (B = 0·141, P < 0·01) and from protein (B = –0·171, P = 0·02). Body weight was also lower at week 12 in intervention groups compared with control (B = –0·377, P < 0·05), but associations with %FS were weak. Our findings demonstrate the benefit of dietary recommendations for reducing FS intakes in UK adults. Limited advantages were found for the different dietary recommendations, but variety may offer individual choice.

To meet the 2030 goal to end all types of malnutrition, thoroughly investigating and addressing context-specific factors of undernutrition is crucial. Therefore, this study assessed the prevalence of undernutrition and associated factors among children aged 6–23 months in South-East Ethiopia. A community-based cross-sectional study was conducted on 580 randomly sampled mother–child pairs in February 2022. Socio-demographic, dietary intake, household food security (HFS), maternal knowledge and practices of child feeding, and the child's weight and height data were collected. A multivariable logistic regression analysis was done. The prevalence of stunted, wasted, and underweight children was 32⋅1, 7, and 9 %, respectively. Being male (AOR = 1⋅75), not using the growth monitoring and promotion (GMP) service (AOR = 1⋅50), household food insecurity (HFI) (AOR = 1⋅67), lack of improved water (AOR = 2⋅26), and bottle-feeding (AOR = 1⋅54) were significantly associated with stunting. Being male (AOR = 3⋅02), having low maternal knowledge on child-feeding practices (AOR = 3⋅89), not listening to the radio/television (AOR = 3⋅69), having a history of fever (AOR = 3⋅39), bottle-feeding (AOR = 3⋅58), and HFI (AOR = 3⋅77) were significantly predicted wasting. Being male (AOR = 3⋅44), not using GMP service (AOR = 2⋅00), having a history of fever (AOR = 4⋅24), lack of knowledge on optimal breastfeeding duration (AOR = 3⋅58), low maternal knowledge on child feeding (AOR = 2⋅21), HFI (AOR = 2⋅04), and lack of improved water (AOR = 3⋅00) showed significant association with underweight. In conclusion, stunting is alarmingly common while wasting and underweight are sub-optimal. Prevention of infectious disease, providing basic education for fathers, ensuring HFS; enhancing media access, maternal knowledge about IYCFP and improving water access; and GMP service utilisation are crucial to improve child nutrition.

Our contributions examine the Norwegian Karl Evang's (1901-1981) and the Dane Halfdan Mahler's (1923-2016) participation in international health co-operation facilitated by the World Health Organization (WHO) in India in the 1950s. While Evang’s was a hectic, but relatively short visit as part of a WHO visiting team of medical scientists in 1953, Mahler’s spanned the entire decade on assignments as WHO medical officer to tuberculosis control projects. Mahler’s name should be familiar to researchers of international health as the Director-General of the WHO 1973-88, and for his promotion of primary health care through the 1978 Alma-Ata Declaration. Evang, Norway’s Director of Health 1938-72, was also a key figure in international health in the mid-twentieth century as one of the original instigators of the WHO, and a participant in much of its early work.

A core theme is the place of social medicine, both in Evang’s and Mahler’s work, and within the WHO and its navigation of complex postcolonial settings in the 1950s. Investigating cross-regional encounters and circulations of social medicine ideas between Evang and Mahler and their Indian interlocutors as well as international WHO staff members, we ask what the role of social medicine was in international health in the early post-war period. Researchers have found that social medicine had its heyday during the 1930s and 1940s, and that a technology-focused, vertical approach became dominant soon after the war. In contrast, we suggest that continued circulation of social medical ideas points towards a more complicated picture.

The present paper outlines current issues in the nutritional care of women during pregnancy and potential resources to address them. Globally, overnutrition, undernutrition and nutritional imbalances are widespread among women of reproductive age; increasing the risk of pregnancy complications and non-communicable diseases in both mothers and their children. Most women do not meet dietary guidelines for pregnancy. The World Health Organisation (WHO) recommends nutrition and weight counselling during pregnancy for all women. However, clinical practices focusing on nutrition vary and there is no consensus on which outcomes are most important for pregnancy nutrition interventions, with little consideration for the ‘patient voice’. The International Federation of Gynaecology and Obstetrics (FIGO) nutrition checklist is a clinical practice tool that is available for healthcare professionals that will address this issue. The pregnancy nutrition core outcome set will also support advancement of antenatal nutrition by identifying the most critical nutrition-related outcomes from the perspective of healthcare professionals, researchers and women with experience of pregnancy. While poor nutrition can result in adverse outcomes across women of all weight categories, those with obesity may require specialist care to reduce their risk. Obesity is a chronic, progressive, relapsing disease that has high individual variability in its prognosis. The use of obesity staging systems, which consider mental, physical and functional health, can stratify individuals into risk categories and aid in treatment prioritisation in pregnancy. As the prevalence of obesity continues to rise, an obesity staging approach may support clinicians, especially those in limited resource settings.

Analyses related to the Covid-19 pandemic have mainly addressed measures adopted in response to this event without paying attention to provisions included in the 2005 International Health Regulations which require States to develop predefined core capacities to prevent, control and provide a public health response to the international spread of disease. The legal architecture related to these obligations has, however, various shortcomings and States have largely failed to implement the required measures. Only recently has some practice been developed by the WHO to address these deficiencies, and further action is still required to finally implement this (neglected) cornerstone of the global health system.

In 1965 Jamaica was declared free of malaria by the World Health Organisation (WHO), thus ending centuries of death and suffering from the disease. This declaration followed the successful completion of the WHO’s Malaria Eradication Programme (MEP) on the island, initiated in 1958. This account first explores the antecedent control measures adopted by the government up to the MEP. These, as advocated by the previous malaria ‘experts’ who had reported on the disease on the island concentrated on controlling the vector and the administration of quinine for individual protection. Although Jamaica suffered no catastrophic epidemics of island-wide scope, malaria was a constant cause of mortality and morbidity. Major change came in the wake of the Second World War within the changing political context of national independence and international development. In 1957 the Jamaican government joined the global WHO programme to eradicate malaria. The Jamaican campaign exposes many of the problems noted in other studies of such top–down initiatives in their lack of attention to the particular circumstances of each case. Despite being described as ‘a textbook pattern’ of malaria eradication, the MEP in Jamaica suffered from a lack of sufficient preparation and field knowledge. This is most obviously illustrated by the fact that all literature on the programme sent to Jamaica in the first two years was in Spanish. That the MEP exploited the technological opportunity provided by dichlorodiphenyltrichloroethane (DDT) with advantage in Jamaica is not disputed but as this analysis illustrates this success was by no means guaranteed.

In the course of the twentieth century road traffic injuries (RTIs) became a major public health burden. RTI deaths first increased in high-income countries and declined after the 1970s, and they soared in low- and middle-income countries from the 1980s onwards. As motorisation took off in North America and then spread to Europe and to the rest of the world discussions on RTIs have reflected and influenced international interpretations of the costs and benefits of ‘development’, as conventionally understood. Using discourse analysis, this paper explores how RTIs have been constructed in ways that have served regional and global development agendas and how ‘development’ has been (re-)negotiated through the discourse of RTIs and vice versa. For this purpose, this paper analyses a selection of key publications of organisations in charge of international health or transport and places them in the context of (a) the surrounding scientific discussion of the period and (b) of relevant data regarding RTI mortality, development funding, and road and other transport infrastructure. Findings suggest that constructions of RTIs have shifted from being a necessary price to be paid for development to being a sign of development at an early stage or of an insufficiently coordinated development. In recent years, RTI discussions have raised questions about development being misdirected and in need of fundamental rethinking. At present, discussions are believed to be at a crossroads between different evaluations of developmental conceptualisations for the future.
