The nutritional profile of older men living in Sydney, Australia: a preliminary analysis of data from the Concord Health and Ageing in Men Project (CHAMP) Author: Rosie Waern (PhD candidate) Co-Authors: Robert Cumming, Vasikaran Naganathan, Fiona Blyth, Margaret Allman-Farinelli, Jean Reid, Vasant Hirani CHAMP Large longitudinal study of health of older men 1705 men initially involved - ~50% response rate Men re-examined after 2 and 5 years + 4 monthly calls (falls, fractures or hospitalisations) Follow up for 5 more years Participants Community dwelling men aged 75+ Selection criteria: No nursing home Living in Burwood, Canada Bay and Strathfield - near the Concord Hospital, Sydney From various cultural backgrounds Australian, Italian, Greek, Chinese, etc. CHAMP recruitment Invitation letter sent to 3627 men identified from electoral roll Contact made with 3005 men 1511 men agreed to participate + 194 men volunteered to participate 1705 men at Baseline ~1000 men remaining at 5 year follow-up 324 men completed Diet History ~622 men did not have listed telephone number Measurements in the CHAMP Methods: Dietary 1 Diet history interview (past three months intake) Contacted after attending 5 year follow up clinic; Takes ~40min Conducted by dietitian at participants’ residence Encourage wife to participate in interview Use of food models to assist in quantification and memory Checklist of “extra foods” and snacks Preliminary validation shows excellent correlation (WFR vs. DH) Methods: Dietary 2 Information on all the macro and micronutrients FoodWorks7 pro, AUSNUT 2007 database - most recent and complete nutrient database Nutrients of interest (protein, calcium, iron, zinc, vitamins A, C and D) were compared to Australian Nutrient Reference Values (NRV) - Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR) were used according to sex and age (Male, 70y+) Methods: Statistics SPSS and STATA Logistic regression Means and SDs Proportion of men meeting NRVs Results: means and macronutrients distribution Macronutrient distribution Alcohol 4% Others 4% Protein 20% Total fat 35% Carbohydrate 37% Sat. Fat 12% Other fats 23% Acceptable Macronutrient Distribution Range (AMDR) 15-25% from protein 45-65% from carbohydrate 20-35% from fats ≤10% of this as saturated fats Mean age was 81yo (±4.5y) Mean BMI was 27.6 kg/m2 (±4kg/m2) Mean energy intake was 9013kJ(SD 2297kJ) Total fat contribution on its upper limit Saturated fat contribution was 2% higher than recommended Carbohydrate contribution was lower than recommended A large number of men consuming limited amounts of carbohydrate Contribution of nutrients: fat 37kJ/g, carbohydrate 17kJ/g, protein 17kJ/g Results - Mean intake vs. Nutrient Reference Values (NRVs) Vit A (µg) Zinc (mg) 1500 15 14 13 14.2 12 1000 Intake EAR 12 11 1.5 1154 500 10 16 123 12 Intake 27.5 EAR 6 Calcium (mg) 20 Intake 28 Intake Vit D (µg) 30 29 16 0 Dietary fibre (g) 30 EAR Iron (mg) 4 30 0 0.83 0.5 8 EAR 50 Intake 0 Vit C (mg) 100 26 EAR 625 1.34 1 Intake 0 150 27 Protein(g) AI 1500 15 15 10 5 0 Intake AI 6.3 1000 500 0 897 1100 Intake EAR Results: Percentage of men meeting Nutrient Reference Values (NRVs) 98.5% 100.0% 90.0% 99.1% 90.7% 83.3% 80.0% 70.0% 66.0% 60.0% 50.0% 40.0% 33.6% 30.0% 22.5% 20.0% 10.0% 1.5% 0.0% Met NRV Vit A Vit C Vit D Calcium Iron Zinc Dietary Fibre Protein Results: Food sources Beef - protein and zinc; Milk - for calcium; vitamin D, vitamin A; Breakfast cereals iron; Vegetables - dietary fibre and vitamin C Results: Others Men aged ≥85yo ↑protein, calcium, iron and zinc intakes compared to those aged 75-79. There were no significant associations between country of birth, occupation, education status and any macro- or micronutrients. Strengths and Limitations Strengths A range of information on health of older men (self reported biological, clinical) – look at more associations between nutrition and various outcomes Reliable dietary method – very good correlation between diet history and weighed food records (preliminary results) Only few studies have used Diet History Limitations Preliminary results - full data set at the end of year Next step Associations of oral health and nutrition A more comprehensive nutritional profile of these men Association of macronutrient intake and health outcomes - The geometric framework and nutrition of older men (my PhD) And much more… Acknowledgements All the CHAMP team and participants Prof Bob Cumming Dr Vasant Hirani NHMRC CEPAR CERA AARF Thank you
