Nutrition in adolescent growth and development
Vitamin D deficiency causes rickets in an urban informal settlement in Kenya and is associated with malnutrition
The commonest cause of rickets worldwide is vitamin D deficiency, but studies from sub-Saharan Africa describe an endemic vitamin D-independent form that responds to dietary calcium enrichment. The extent to which calcium-deficiency rickets is the dominant form across sub-Saharan Africa and in other low-latitude areas is unknown. We aimed to characterise the clinical and biochemical features of young children with rickets in a densely populated u…
Dietary intake and body composition in HIV-positive and -negative South African women
Objective The present paper examines dietary intake and body composition in antiretroviral (ARV)-naïve HIV-positive compared with HIV-negative South African women, as well as the impact of disease severity on these variables. Design Baseline data from a longitudinal study assessing bone health in HIV-negative and HIV-positive premenopausal South African women over 18 years of age were used. Anthropometry and body composition, measured by dual ene…

Evidence for a downward secular trend in age of menarche in a rural Gambian population
Menarcheal age is a key indicator of female maturity and development. Studies in many countries have reported a downward secular trend in age of menarche over the past century. This study presents data gained using the 'status quo' method and interval regression to estimate median menarcheal age of girls in a rural Gambian community. Cross-sectional studies carried out in 1989, 2000 and 2008 revealed a median menarcheal age of 16.06 (95% CI 15.67…
Dependence of blood indices of selenium and mercury on estimated fish intake in a national survey of British adults
Objective Contributions of fish and other foods to variance of selenium and mercury status were studied in British adults. Setting and design Plasma and red-cell selenium and whole-blood mercury concentrations were measured during the National Diet and Nutrition Survey of Adults aged 19–64 years in mainland Britain, 2000–2001 ( n = 1216). Food intake was weighed for seven consecutive days, and foods were combined in groups for data analysis. Four…
Intake and sources of phylloquinone (vitamin K 1 ) in 4-year-old British children
Objective To compare dietary intake and sources of phylloquinone (vitamin K 1 ) in 4-year-old British children between 1950 and the 1990s, and report their variation by sociodemographic factors. Design Nationally representative samples of 4-year-olds from the longitudinal Medical Research Council National Survey of Health and Development (NSHD) (1950) and the cross-sectional National Diet and Nutrition Surveys (NDNS, 1992/93 and 1997). Setting Gr…
Diet, nutrition and the prevention of osteoporosis
Objective: To review the evidence on diet and nutrition relating to osteoporosis and provide recommendations for preventing osteoporosis, in particular, osteopototic fracture. Approach: Firstly, to review the definition, diagnosis and epidemiology of osteoporosis, to discuss the difficulties in using bone mineral density to define osteoporosis risk in a world-wide context and to propose that fragility fracture should be considered as the disease …
Risk factors for low iron intake and poor iron status in a national sample of British young people aged 4–18 years
Objective: To examine the prevalence and dietary, sociodemographic and lifestyle risk factors of low iron intake and poor iron status in British young people. Design: National Diet and Nutrition Survey of young people aged 4–18 years. Setting: Great Britain, 1997. Subjects: In total, 1699 young people provided 7-day weighed dietary records, of which 11% were excluded because the participant reported being unwell with eating habits affected. Blood…
Risk factors for poor iron status in British toddlers
Objective To examine risk factors for poor iron status in British toddlers. Design National Diet and Nutrition Survey (NDNS) of children aged 1.5–4.5 years. Setting Mainland Britain, 1992/93. Subjects Of the 1859 children whose parents or guardians were interviewed, a weighed dietary intake was provided for 1675, and a blood sample obtained from 1003. Results Mean haemoglobin (Hb) and ferritin levels were significantly lower in younger (1.5–2.5 y…
Relationship between cigarette smoking and nutrient intakes and blood status indices of older people living in the UK
Objectives To examine the relationship between cigarette smoking and a range of nutrient intakes and blood status indices in older people. Design National Diet and Nutrition Survey: cross-sectional survey of nationally representative sample of people aged 65 years and over. Setting Mainland Britain during 1994/95. Subjects 1191 people (619 male, 572 female) aged 65 years and over, of whom 920 were living in private households and 271 were living …
An appraisal of vitamin B 6 status indices and associated confounders, in young people aged 4–18 years and in people aged 65 years and over, in two national British surveys
Objective: To compare vitamin B 6 status indices with each other and with potential confounding factors, in the datasets from two national British surveys and associated studies. Design: Vitamin B 6 status was measured by plasma pyridoxal phosphate (PLP) and plasma pyridoxic acid (PA) in both surveys, and also by erythrocyte aspartate aminotransferase activation coefficient (EAATAC) in one of the surveys. Plasma α 1 -antichymotrypsin was measured…
Use of medicines by older people in a large British national survey, and their relation to vitamin status indices
Objective: To describe the extent of use of medicines by older people living in Britain, and to explore relationships with vitamin status indices. Design: The National Diet and Nutrition Survey of people aged 65 years and over collected data from a British sample during 1994–95. The present study has made novel use of it, to relate medicine use with biochemical indices of vitamin status. Setting: Eighty postcode areas, selected randomly from main…
Relationship between alcohol and nutrient intakes and blood status indices of older people living in the UK
Objective: To examine the relationships between alcohol consumption and a range of nutrient intakes and blood status indices in older people. Design: National Diet and Nutrition Survey: cross-sectional survey of nationally representative sample of people aged 65 years or over. Setting: Mainland Britain during 1994/5. Subjects: 1198 people (623 males, 575 females) aged 65 years or over, of whom 925 were living in private households and 273 were li…
