About this study

The investigators aim to investigate the association of midlife dietary and lifestyle factors on cardiac functional changes in the elderly. The investigators hypothesize that even in those without clinically manifest cardiovascular disease, the extent of underlying abnormalities in cardiovascular structure and function in the elderly would be independently related to midlife dietary and lifestyle factors.

Read the detailed description

This proposal will investigate how midlife factors in diet and lifestyle affect various aspects of cardiac structure and function related to ageing. The investigators plan to conduct the study among a sub-cohort of 600 participants from the Singapore Chinese Health Study. Comprehensive information on diet and lifestyle factors had been collected at recruitment and updated in two subsequent follow-up interviews. Candidate nutrition-related blood biomarkers such as vitamins D, homocysteine, fatty acids (short, medium and long-chain) and lipids (LDL, HDL, triglycerides) will be analyzed from samples obtained between 1999 and 2004. The investigators will study effects of smoking, alcohol consumption, sleep duration, physical activity and diet on cardiac ageing. The investigators will study overall dietary pattern, intake of specific items such as fatty acids, soy food, coffee and tea beverages, from validated food frequency questionnaires (FFQ), and nutrients from questionnaire information from this cohort previously obtained.

These nutrient and lifestyle factors will be studied individually, and for their joint or interactive effects on cardiac ageing measurements. Quantitative cardiac ageing-related outcome parameters describing cardiac mass, systolic and diastolic function, and vessel distensibility will be examined by cardiac magnetic resonance imaging. Maximum oxygen uptake (VO2 max) will be calculated based on age, gender, waist circumference, resting heart rate, and exercise habits. Body composition will be analysed by a body composition analyser machine onto which subjects stand on.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiovascular Magnetic Resonance Imaging (MRI)Other

    Cardiovascular MRI uses interaction of the magnetic properties of body tissues with strong magnetic fields to create heart images.

  • EchocardiographyOther

    To measure heart chamber size, heart function, blood vessel size and blood vessel function. These measurements will help us understand the type and severity of heart failure.

  • TonometryOther

    Tonometry is a noninvasive method to obtain arterial pressure waveform

  • Genetic Testing (Blood)Other

    The blood will be stored for genetic tests and development of cell lines to study genetic risks for aging related diseases and cardiovascular disease.

  • Hand-Grip Strength MeasurementOther

    We will measure your hand grip strength using a standard hand dynamometer which is a portable meter that you will use your hands to press on.

  • Body Fat Mass AnalysisOther

    Body composition will be analysed by a body composition analyser machine onto which you will have to stand on.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02791139, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
