Associations between child temperament, maternal feeding practices and child body mass index during the preschool years: a systematic review of the literature

It is a research priority to identify modifiable risk factors to improve the effec- tiveness of childhood obesity prevention strategies. Research, however, has largely overlooked the role of child temperament and personality implicated in obesogenic risk factors such as maternal feeding and body mass index (BMI) of preschoolers. A systematic review of relevant literature was conducted to inves- tigate the associations between child temperament, child personality, maternal feeding and BMI and/or weight gain in infants and preschoolers; 18 papers were included in the review. The findings revealed an association between the temperament traits of poor self-regulation, distress to limitations, low and high soothability, low negative affectivity and higher BMI in infants and preschool- aged children. Temperament traits difficult, distress to limitations, surgency/ extraversion and emotionality were significantly associated with weight gain rates in infants. The results also suggested that child temperament was associated with maternal feeding behaviours that have been shown to influence childhood over- weight and obesity, such as using restrictive feeding practices with children per- ceived as having poor self-regulation and feeding potentially obesogenic food and drinks to infants who are more externalizing. Interestingly, no studies to date have evaluated the association between child personality and BMI/weight gain in infants and preschoolers. There is a clear need for further research into the association of child temperament and obesogenic risk factors in preschool-aged children.

The occupiers' burden: tackling food shortage and related health problems in post-war Germany 1945-47

The end of the Second World War brought much relief to its combatants, but a range of problems remained that would plague post-war Europe for years to come. Chief among them was food shortage. The breakdown of agricultural systems, essential services, and the state itself laid fertile ground for food shortage to develop in parts of post-war Germany occupied by the victorious powers. There is much to be gained from comparing the occupiers’ responses to this Horseman of the Apocalypse. The most fruitful comparison lies between the Soviets and British. Unlike the Americans whose economic might in the post-war period allowed them to better feed and supply Germans living in their occupation zone, domestic economic weaknesses hamstrung both Soviet and British responses to the more severe advent of food shortage which confronted them. Their responses were very different—some successful, others not—but all instructive for understanding the impacts of natural and policy factors on the development of food shortage and the consequences to the health of the population. The variety of these impacts have been obscured by the absence of this comparison in the literature, which is now made more feasible by the greater availability of the extensive resources that each occupier devoted to recording food and health data, particularly in the Soviet case. The data is not only relevant to the occupation period from 1945 to 1949, as it suggests long-term health impacts on those most exposed to the risk of food shortage then, and most at risk to the consequences of malnutrition decades later. In fact, as the available data defines regional differences in food rations and, accordingly, comparative food shortages in Soviet and British occupation zones, the situation in post-war Germany provides an excellent platform for future research linking differences in early nutrition to adult health outcomes.
