Article Synopsis
  • - Dietary intervention studies indicate that flavan-3-ol could boost vascular health and lower cardiovascular disease (CVD) risk, but many long-term studies show mixed results.
  • - The EPIC-Norfolk study analyzed data from nearly 25,000 participants to assess the link between flavan-3-ol intake and blood pressure/CVD risk using food diaries and statistical methods.
  • - Results showed no consistent relationship between flavan-3-ol consumption and blood pressure or CVD events, suggesting that just consuming flavan-3-ols may not significantly reduce CVD risk.

Background: Although ageing is strongly associated with cognitive decline, a wide range of cognitive ability is observed in older populations with varying rates of change across different cognitive domains.

Methods: Cognitive function was measured as part of the third health examination of the European Prospective Investigation of Cancer in Norfolk (EPIC-Norfolk 3) between 2006 and 2011 (including measures from the pilot phase from 2004 to 2006). This was done using a battery consisting of seven previously validated cognitive function tests assessing both global function and specific domains.

Article Synopsis
  • The study analyzed energy, nutrient, and food intake data from 7-day diet diaries (7dDD) of 25,639 participants in the EPIC-Norfolk study, focusing on important methodological challenges.
  • Data showed a mean energy intake of 9.44 MJ/d for men and 7.15 MJ/d for women, with higher micronutrient density in women; however, participants, especially those with a higher BMI, often under-reported their intake.
  • The way food intake data is categorized (crude vs disaggregated) affected the findings, highlighting that while rankings among individuals may remain consistent, the absolute food intake comparisons between different studies can vary significantly.

Background: The European Working Group for Sarcopenia in Older People (EWGSOP) published a case-finding algorithm for sarcopenia, recommending muscle mass measurement in older adults with low grip strength (women <20 kg; men <30 kg) or slow walking speed (≤0.8 m/s). However, the implications of adopting this algorithm into clinical practice are unclear.

In the present study, we investigated the association between dietary intake of carbohydrates and the risk of type 2 diabetes. Incident cases of diabetes (n 749) were identified and compared with a randomly selected subcohort of 3496 participants aged 40-79 years. For dietary assessment, we used 7 d food diaries administered at baseline.

The European Prospective Investigation of Cancer (EPIC) is a 10-country collaborative study in which EPIC-Norfolk is one of the UK centres. EPIC-Norfolk examined 25 639 men and women resident in East Anglia (aged 40-79 years), between 1993 and 1997. The EPIC collaboration was set up to examine the dietary determinants of cancer, but the remit in the EPIC-Norfolk cohort was broadened from the outset to include determinants of other health conditions and chronic diseases.

Objective: A diet rich in phyto-oestrogens has been suggested to protect against a variety of common diseases but UK intake data on phyto-oestrogens or their food sources are sparse. The present study estimates the average intakes of isoflavones, lignans, enterolignans and coumestrol from 7 d food diaries and provides data on total isoflavone, lignan and phyto-oestrogen consumption by food group.

Design: Development of a food composition database for twelve phyto-oestrogens and analysis of soya food and phyto-oestrogen consumption in a populationbased study.

The alcohol-breast cancer association has been established using alcohol intake measurements from Food Frequency Questionnaires (FFQ). For some nutrients diet diary measurements are more highly correlated with true intake compared with FFQ measurements, but it is unknown whether this is true for alcohol. A case-control study (656 breast cancer cases, 1905 matched controls) was sampled from four cohorts in the UK Dietary Cohort Consortium.

The risk for colorectal cancer may be influenced by the dietary intake of various vitamins, minerals and essential fatty acids. We conducted a pooled analysis of dietary data collected using food diaries in seven prospective studies in the United Kingdom Dietary Cohort Consortium. Five hundred sixty-five cases of colorectal cancer were matched with 1,951 controls on study centre, age, sex and recruitment date.

Article Synopsis
  • The study investigated how physical activity relates to ocular perfusion pressure (OPP), a known risk factor for glaucoma, in over 5,600 participants aged 48 to 90 from the EPIC-Norfolk study.
  • Results showed that active individuals had a significantly lower risk of experiencing low mean and diastolic OPP after adjusting for various factors like age and body mass index.
  • The findings suggest that being physically active may help maintain better OPP levels, indicating a need for more research on how increasing physical activity could potentially lower glaucoma risk.

Background: Epidemiologic studies of dietary fat and breast cancer risk are inconsistent, and it has been suggested that a true relation may have been obscured by the imprecise measurement of fat intake.

Objective: We examined associations of fat with breast cancer risk by using estimates of fat intake from food diaries and food-frequency questionnaires (FFQs) pooled from 4 prospective studies in the United Kingdom.

Design: A total of 657 cases of breast cancer in premenopausal and postmenopausal women were matched on study, age, and recruitment date with 1911 control subjects.

Objective: To determine whether the full Mini Mental State Examination (MMSE) scale range can be derived from an abbreviated 11-item version that was designed for testing general cognitive function in a cohort where only a small proportion were expected to be severely impaired or demented.

Study Design And Setting: Using simple computation and multiple imputation, the properties of the abbreviated MMSE were compared with the full MMSE score using data from the Medical Research Council Cognitive Function and Ageing Study.

Results: Full MMSE scores can be generated for the abbreviated version by assuming high functioning on excluded items.

Objective: Supplements are an important source of micronutrient intake, which, unless taken into account, can misclassify individuals with regard to levels of nutrient exposure. A label-based vitamin and mineral supplements (ViMiS) database was developed to contain manufacturers' information and to enter supplement use by participants in the European Prospective Investigation into Cancer and Nutrition in Norfolk (EPIC-Norfolk). The ViMiS database contains information on all ingredients, broken down into nutrient information in order to be combined with nutrient intake derived from food consumption.

Background: Iron deficiency anaemia is a common paediatric problem worldwide, with significant neurodevelopmental morbidity if left untreated. A decrease in the mean corpuscular volume (MCV) can be used as a surrogate marker for detecting early iron deficiency prior to definitive investigation and treatment. An audit cycle was therefore undertaken to evaluate and improve the identification, follow-up and treatment of abnormally low MCV results amongst the paediatric inpatients in an English district general hospital.

In this large cross-sectional study, we investigated the relationship between phytoestrogen exposure and circulating sex hormones and sex hormone-binding globulin (SHBG) levels in 1988 healthy postmenopausal women and their interactions with polymorphisms in genes involved in estrogen signaling. Plasma estradiol, testosterone, androstenedione, estrone, and SHBG were measured. Urinary levels of five isoflavones (daidzein, genistein, glycitein, O-desmethylangolensin, and equol) and two lignans (enterodiol and enterolactone) were measured and used as biomarkers for dietary intakes.
