      Abstract

      Dietary modifications can improve serum lipids and reduce cardiovascular disease (CVD) risk. However, attendance at multiple dietary consultations can be a barrier to achieving behaviour change. This study investigated the effectiveness of a brief dietetic intervention on CVD risk factors in hyperlipidaemic adults. Adults with total cholesterol ≥ 5.0 mmol/L or low density lipoprotein (LDL) cholesterol ≥ 4.0 mmol/L and not currently taking lipid-lowering medication were eligible for a minimum 6-week dietary intervention. Dietary intake data and blood lipids were acquired prior to a single counselling session with an Accredited Practising Dietitian (APD). The intervention used targeted feedback with purpose-developed education materials to supplement advice. CVD risk factors and dietary intakes were used to assess pre-post intervention change using linear mixed model regression analyses. Thirty-nine participants (59.3 ± 11.1 years, n = 28 female) were analysed. Mean ± SD follow-up from baseline time was 9.5 ± 2.5 weeks. Significant (p < 0.05) reductions in total cholesterol (−0.51 mmol/L), total:HDL (high density lipoprotein) ratio (−0.27 mmol/L), triglycerides (−0.38 mmol/L), total energy (−870 kJ/day), energy from nutrient-poor foods (−1006 kJ/day) and sodium (−325 mg/day), and improved dietary fat quality (−5.1% of energy/day saturated, +5.0% of energy/day polyunsaturated) and body mass index (−0.4 kg/m2) were achieved. A brief intervention by an APD incorporating targeted, personalised dietary feedback and education in a single counselling session can improve lipid profiles in adults with hyperlipidaemia.

      International physical activity questionnaire: 12-country reliability and validity.

      Physical inactivity is a global concern, but diverse physical activity measures in use prevent international comparisons. The International Physical Activity Questionnaire (IPAQ) was developed as an instrument for cross-national monitoring of physical activity and inactivity. Between 1997 and 1998, an International Consensus Group developed four long and four short forms of the IPAQ instruments (administered by telephone interview or self-administration, with two alternate reference periods, either the "last 7 d" or a "usual week" of recalled physical activity). During 2000, 14 centers from 12 countries collected reliability and/or validity data on at least two of the eight IPAQ instruments. Test-retest repeatability was assessed within the same week. Concurrent (inter-method) validity was assessed at the same administration, and criterion IPAQ validity was assessed against the CSA (now MTI) accelerometer. Spearman's correlation coefficients are reported, based on the total reported physical activity. Overall, the IPAQ questionnaires produced repeatable data (Spearman's rho clustered around 0.8), with comparable data from short and long forms. Criterion validity had a median rho of about 0.30, which was comparable to most other self-report validation studies. The "usual week" and "last 7 d" reference periods performed similarly, and the reliability of telephone administration was similar to the self-administered mode. The IPAQ instruments have acceptable measurement properties, at least as good as other established self-reports. Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings. The short IPAQ form "last 7 d recall" is recommended for national monitoring and the long form for research requiring more detailed assessment.

          Primary prevention of cardiovascular disease with a Mediterranean diet.

          Observational cohort studies and a secondary prevention trial have shown an inverse association between adherence to the Mediterranean diet and cardiovascular risk. We conducted a randomized trial of this diet pattern for the primary prevention of cardiovascular events. In a multicenter trial in Spain, we randomly assigned participants who were at high cardiovascular risk, but with no cardiovascular disease at enrollment, to one of three diets: a Mediterranean diet supplemented with extra-virgin olive oil, a Mediterranean diet supplemented with mixed nuts, or a control diet (advice to reduce dietary fat). Participants received quarterly individual and group educational sessions and, depending on group assignment, free provision of extra-virgin olive oil, mixed nuts, or small nonfood gifts. The primary end point was the rate of major cardiovascular events (myocardial infarction, stroke, or death from cardiovascular causes). On the basis of the results of an interim analysis, the trial was stopped after a median follow-up of 4.8 years. A total of 7447 persons were enrolled (age range, 55 to 80 years); 57% were women. The two Mediterranean-diet groups had good adherence to the intervention, according to self-reported intake and biomarker analyses. A primary end-point event occurred in 288 participants. The multivariable-adjusted hazard ratios were 0.70 (95% confidence interval [CI], 0.54 to 0.92) and 0.72 (95% CI, 0.54 to 0.96) for the group assigned to a Mediterranean diet with extra-virgin olive oil (96 events) and the group assigned to a Mediterranean diet with nuts (83 events), respectively, versus the control group (109 events). No diet-related adverse effects were reported. Among persons at high cardiovascular risk, a Mediterranean diet supplemented with extra-virgin olive oil or nuts reduced the incidence of major cardiovascular events.
