Childhood overweight and obesity are a global public health problem. In high-income countries, obesity follows socioeconomic patterns, in that people with a lower socioeconomic position are more likely to be overweight or obese than those with a higher socioeconomic position. Poor diet is a key risk factor for excess weight gain. It is also a risk factor that we can do something about.
Reducing child mortality remains one of the key objectives of the Sustainable Development Goals. Remarkable progress has been made over the past 25 years, with the global number of deaths of children aged under 5 falling from 13 million in 1990 to six million in 2015. Yet little is known about the relative contributions of specific public health interventions and general improvements in socioeconomic status and educational attainment over the same period.

Traditionally, asthma and type 1 diabetes have been considered distinct immune-mediated diseases in which the underlying immune responses counteract each other, resulting in an inverse association between the diseases. In our study, recently published in the IJE, we explored the association between asthma and type 1 diabetes in childhood in a novel way, and observed that the direction of the association is dependent on the order of appearance of the diseases.

In low- and middle-income countries, the odds of surviving the first 28 days of life are grossly unequal between infants born in deprived and better-off families, even among children living in the same community. In our study, recently published in the IJE, we have shown that women’s groups are able to address this problem. Under the guidance of a facilitator, women came together every month to discuss problems during pregnancy, delivery and the newborn period, and then designed and implemented strategies to overcome these problems with the help of the entire community.

For some years, our research has been based in the city of Bradford in northern England. We are often asked to justify our research setting. There seems to be a concern that a cohort population that is not representative of the nation as a whole or of the ‘average person’ cannot produce valuable insights beyond its local setting.
While such concerns are not new, they now seem more present, perhaps due to the rise of Big Data or the increased sharing of and access to data from national surveys and cohorts. Do these reservations represent a push for representativeness and generalisability in epidemiology? If so, this might come at the expense of research aiming to paint a more detailed picture of population health.

Our study, recently published in the IJE, looks at the relationship between pre-gestational weight status and children’s neurodevelopment. It shows that children born to mothers who were normal weight before pregnancy scored better on cognition tests than children born to obese women. An original aspect of our study is that it summarises the evidence provided by 15 previous follow-up studies, including samples from seven different countries, and provides information for both cognition tests and general intelligence scores.

A new study shows that asthma is three times more common in those who had a father who smoked in adolescence, and twice as common in those whose father worked with welding before conception. Can these numbers be reduced by including adolescent boys in public health prevention programmes?
It is well known that a mother’s environment plays a key role in child health. The hypothesis that health and disease originate early in life has dramatically increased our understanding of this issue. However, recent research suggests that this may also be true for fathers; i.e. father’s lifestyle and age appear to be reflected in molecules that control gene function. There is growing evidence from animal studies for “epigenetic” inheritance, a mechanism whereby the father’s environment before conception could impact on the health of future generations.

From 2010 to 2012 a P4P programme in Afghanistan provided quarterly bonus payments to health-care providers for increases in the use of maternal and child health (MCH) services, adjusted by a quality of care score. Our study, a large-scale cluster randomized trial, demonstrates that the programme did not produce the intended results. There were no observable improvements in any of the five key MCH coverage indicators measuring contraceptive prevalence, skilled birth attendances, vaccinations, and antenatal and postnatal check-ups. No changes were observed in the equity of care. While the programme appeared to increase time spent with patients, resulting in more complete histories and physical examinations, and improved patient counselling, other measures of quality, such as availability of medicines and supplies, did not substantially change.
