“…The British Household Food Consumption and Expenditure Surveys provide data for calcium and iron but make no reference to magnesium in over 200 pages (Ministry of Agriculture, Fisheries and Food, 1985). A dietary survey of British schoolchildren sponsored and published by DHSS in 1986 did not collect or publish any data on magnesium (Wenlock et al, 1986). White bread in Britain is fortified with calcium but not with magnesium although calcium is reported to aggravate the effects of magnesium deficiency (Seelig, 1980, p. 353-356).…”

7.2 per cent of babies born in England and Wales in 1986 had birthweights below 2,500 g. Low birthweight and hypertension are associated. European trials have reported that oral supplementation with physiological amounts of magnesium during pregnancy reduces pregnancy hypertension and also miscarriage, preterm birth and fetal growth retardation. Magnesium deficiency causes hypertension and low birthweight in animals. In humans deficiency of thiamin and other B vitamins has also been reported to cause pregnancy hypertension and low birthweight. Magnesium and B vitamins are essential for the same biochemical reactions in energy metabolism. There is evidence that magnesium consumption of substantial numbers of women in Europe and North America is too low to support a healthy pregnancy. Magnesium and thiamin are lost in processing many foods. British trials of magnesium supplementation are advocated. It is suggested that more attention should be given to magnesium in nutritional advice.

“…1983. A survey by Wenlock et al (1986) of schoolchildren's diets gave height and weight figures for about 890 boys and 810 girls aged' 10/11', and 510 boys and 450 girls aged' 14/15'; it was again conducted by the OPCS but based on a sample of schools (excluding independent schools). The ages were chosen in relation to adolescence-at the upper end after most boys would have started their spurt in growth, at the lower end before the onset of menarche in most girls.…”

SUMMARY Height and weight data for Great Britain exist back to 1883 (Report of the Anthropometric Committee of the British Association) and even before. These have been reviewed up to the present date: in particular, a long series for army recruits has been analysed, helping considerably in establishing a trend, and recent surveys have established a secure base for future comparisons at national level. But many other sets of data fit the general pattern of increasing heights and weights over the past century at all ages. Quetelet's index w/h2 is recommended as a good indicator of ‘weight for height’ in adult populations; for children it is still at the descriptive stage. A method is suggested for calculating the index and its limits when the complete distribution of heights and weights is unknown, as in many historical series. Finally, class differences are investigated and appear to have narrowed over a century.

Children as consumers – snacking behaviour in primary school children

Eighty‐four primary school children (the majority aged 7–8 years), from four schools, two in England and two in Scotland, were surveyed to identify snacking behaviour and the influences on perception and choice of snack foods. A questionnaire plus short interview with activity tasks was adopted, covering general snacking habits and a look at six specific groups of snacks comprising three of ‘unhealthy’ image and three with intermediate or fully ‘healthy’ image. The results showed that, for this age group, there was an overall preference for sweets, crisps and chocolate and less liking for fruit and cereal‐containing snacks. Attitudes to sensory properties showed that ‘taste’ was the main reason for snack choices, usually in spite of a ‘healthy’ image belief for the snacks. Choice was also dependent on parental influence and availability. Gender and relative socio‐economic level differences were minimal, but regional variations showed higher snacking frequency for the Scottish group, which also had fewer children preferring fruit. Meal patterns had little effect on snacking, but inclusion of a prepared meal at lunchtime may have reduced snacking frequency.
