We describe the performance of a new, self-assessment questionnaire that aims to measure pubertal status by using gender-specific line drawings of the Tanner puberty stages. The study was carried out on 103 children aged 12-16 years attending a paediatric endocrinology outpatient clinic and used physical examination by clinic doctors as the 'gold standard'. Of 133 consecutive, eligible children, 108 (81%) agreed to participate in the study. Data were collected from 62 (60%) males and 41 (40%) females. Mean age was 14.78 years (SD = 1.26 years, range 12.08-16.98 years). For the pubic hair distribution Tanner stage, there was agreement to within one Tanner stage for 90 children (88%), weighted kappa statistic for inter-rater agreement = 0.68 [95% CI 0.49,0.87]. For the female breast/male genitalia Tanner stage, there was agreement to within one Tanner stage for 75 children (76%), kappa = 0.48 [95% CI 0.31,0.64]. The children tended to underestimate their stage of pubertal development. Overall, the kappa statistics implied good agreement for the pubic hair question and moderate agreement for the breast/genitalia stage question in both girls and boys. The questionnaire may prove useful in situations such as large-scale epidemiological studies, in which direct examination of children to determine pubertal status is not possible, and further validation in normal adolescents is warranted.

Breastfeeding is associated with increased mean TC and LDL levels in infancy but lower levels in adulthood/adult life. These results suggest that breastfeeding may have long-term benefits for cardiovascular health and may have implications for the content of formula feed milks.

simple explanation. However, a larger study is required to establish new references. The latest British growth standards were developed in 1990, but less than a decade later it has become evident that these standards no longer reflect the distribution of weight in British schoolchildren.The cause for concern is twofold. Firstly, cohort studies show that obesity may track from childhood to adulthood, where morbidity is very evident. Secondly, obesity in adolescence is directly associated with increased morbidity and mortality in adult life independent of adult body weight. This study lends further support to reports that levels of obesity in Britain are increasing at an appreciable rate in primary school children, that the measures of skinfold at the triceps need to be revalidated, and that this major public health issue needs urgently addressing in young children.

The relation of fetal nutrition to TC appears to be weak and is probably of limited public health importance when compared with the effects of childhood obesity.

The predisposition to Type 2 diabetes observed in South Asian adults is apparent before adult life. Establishing the contributions of the childhood and fetal environments and of genetic factors to the development of these ethnic differences is an important priority. Prevention of Type 2 diabetes in British South Asians needs to begin before adult life.

3921 adults randomly selected from across Great Britain were interviewed. Subjects were asked to assess a selection of 10 out of 200 vignettes. Each vignette contained four elements: a category of individual; access to some or all of the health record; specified purpose; and level of patient identifier. Subjects were asked to say how happy they would be to allow access to their health record in the circumstances described.The public were generally happy to provide access to health information. For almost a third of vignettes, subjects said that they would be very happy to allow access to their health information. 9.1% of subjects said that they would be very happy to allow access within all of the vignettes that they were asked to assess. There was however, a significant minority of responses (11.6%) to vignettes where subjects said that they would be very unhappy to allow access. In addition 2.1% of individuals said that they were very unhappy with all of the vignettes presented to them. Individuals from higher social groups, older people and males were more likely to be happy with access to their health information. The individual requesting information was the most important factor determining permission to access health information. Subjects were happier to release anonymised rather than personally identifiable data. Content of the information to be released did not seem to be that important, even when the health record contained sensitive information. With the exception of teaching students, the use of the information wasn't an important determinant of consent.Despite a level of support for use of health information in most circumstances, this doesn't mean that patients don't want to be asked for consent, nor that the views of the small minority can be ignored. The ethical and policy implications of these findings will be discussed.
