Intake of key chronic disease-related nutrients among baby boomers

Micronutrient Intakes of British Adults Across Mid-Life: A Secondary Analysis of the UK National Diet and Nutrition Survey

Background: There is a tendency to report micronutrients intakes collectively for adults, with broad age ranges being used. This means that certain sub-population groups such as young adults are often overlooked. The objective of the present article was to derive and evaluate micronutrient intakes across UK adults in their twenties, thirties, forties and fifties. Methods: A secondary analysis of the UK National Diet and Nutrition Survey (years 1-6) was undertaken. Data from n = 3,238 adults was analyzed and micronutrient intakes from food sources (excluding supplements) derived as a percentage of the Reference Nutrient Intake (RNI) and percentage below the Lower Reference Nutrient Intake (LRNI) for males and females aged 20-29, 30-39, 40-49, and 50-59 years. Mean intakes were used in instances where this data was unavailable (for vitamins D and E). Results: Sizeable gaps were found for magnesium with 19% of young people in their twenties having intakes below the LRNI. Amongst UK females intakes of 9 micronutrients (riboflavin, vitamin B6, B12, folic acid, calcium, iron, magnesium, potassium, and iodine) were significantly lower than males aged 20-59 years (p < 0.001) expressed as a percentage of the RNI. Young adults in their twenties had significantly lower (p < 0.05) intakes of 8 micronutrients (vitamin A, riboflavin, folic acid, calcium, magnesium, potassium, iodine, and copper) expressed as a percentage of the RNI compared with adults in their thirties, forties and fifties. There were also considerable gaps in dietary selenium intakes with 50.3% females and 25.8% males having total intakes beneath the LRNI. A quarter of women had iron (25.3%) and potassium (24.3%) intakes below the LRNI. Conclusions: UK females and younger adults appear to be particularly vulnerable to micronutrient shortfalls from food sources alone. Clearly, improvements in dietary quality are needed across mid-life. Alongside this, fortification and supplementation strategies may be considered to help adults achieve dietary targets at this life-stage when they should be at their nutritional prime.

Characteristics of older adults with diabetes: What does the current aged care resident look like?

AIM

The prevalence of diabetes in older adults in residential aged care (RAC) is twice that of community dwelling older adults. Older adults with diabetes have been highlighted as being at high risk of frailty and malnutrition, particularly when managed on a therapeutic diet. However, assumptions may be based on clinical presentation of our oldest old which may be at conflict with the clinical presentation of younger older adults. The aim of this retrospective audit was to identify the characteristics of aged care residents with diabetes, their comorbidities and malnutrition risk.

METHODS

Residents' with diabetes paper-based records were audited for demographic data, diet code, medical and medication history, malnutrition risk screening scores and anthropometric data.

RESULTS

A total of 295 residents with diabetes records were audited across 13 sites in South Australia. Younger older adults (65-74 years) were generally in a healthy weight range (23-30 kg/m² ) or obese (>30 kg/m² ) and had gained weight since admission to RAC; whereas the oldest old were more likely to have lost weight and had a lower body mass index range 22.6-28.9 kg/m² . An unexpected finding was the variability between RAC sites in dietary management of diabetes and potential inappropriate dietary management of malnutrition, as indicated by their food service diet codes.

CONCLUSIONS

Findings suggest that younger older adults in RAC are more likely to be overweight which is maintained over a typical length of stay. Study findings indicate that diabetes management is inconsistent and highlights the need for mandated RAC menu guidelines.

Retirement and Healthy Lifestyle: A National Health and Nutrition Examination Survey (NHANES) Data Report

BACKGROUND

The objective of this study was to compare the rates of healthy lifestyle adherence among retired late-middle-aged adults with rates among those who are still working.

METHODS

A national cross-sectional study using data from the National Health and Nutrition Examination survey (NHANES). The main outcome was the proportion of retires versus nonretirees who were adherent to ideal or intermediate goals of the American Heart Association's Life's Simple 7, cardiovascular factors including physical activity, healthy diet, healthy weight, smoking status, total cholesterol, glucose, and blood pressure.

RESULTS

Retirees were more likely than nonretirees to have poorly controlled blood pressure (23.9% vs 15.1%; P = .05). However, there were no differences in healthy weight, smoking rates, healthy diet, or glucose or cholesterol control (P > .05). In controlled logistic regression analyses, retirees were more likely to be physically active than nonretirees (odds ratio, 1.85; 95% confidence interval, 1.11-3.09), but were not more likely to be following any other Life's Simple 7 factors.

CONCLUSIONS

Retired adults were more likely to be physically active but were not more likely to be adhering to most of the Life's Simple 7 lifestyle and cardiovascular risk factors. More public health attention to encouraging healthy lifestyles during the transition into retirement may be warranted.

Cardiovascular Health Status in Baby Boomers with Diabetes Mellitus

OBJECTIVES

The objective of this study was to assess the cardiovascular health status of baby boomers with diabetes mellitus (DM) in comparison to the same-age population with DM 10 years previously.

METHODS

The study was conducted in baby boomers with DM using data from the National Health and Nutrition Examination Survey (NHANES) 2009-2012 compared with NHANES 1999-2002. Cardiovascular health metrics were derived from the American Heart Association's Life's Simple 7. The primary outcome was the comparison of the proportion of individuals with each characteristic, including healthy diet, healthy weight, not smoking, exercising regularly, and maintaining an optimal level of glycated hemoglobin (HbA1C), cholesterol, and blood pressure.

RESULTS

Current baby boomers with DM (NHANES 2009-2012) had more obesity (70.9% vs 58.8%; P = 0.009) and a lower proportion of ideal physical activity (20.9% vs 31.7%; P = 0.01) than people of the same age 10 years ago; fewer than 1% adhere to an ideal healthy diet. Current baby boomers more often had ideal cholesterol (59.4% vs 47.2; P = 0.01) and reached an ideal HbA1C (51.0% vs 43.4%; P = 0.047). Blood pressure control, adherence to ideal diet, and smoking rates were not significantly different from 10 years ago. In logistic regression analyses controlling for likely confounders, baby boomers persisted in having more obesity and exercising less often, and reaching an ideal cholesterol level more often (P < 0.01).

CONCLUSIONS

Although improving in cholesterol and HbA1C, baby boomers demonstrated worsening in several key cardiovascular health indicators, particularly obesity and physical activity.

Association of high dietary saturated fat intake and uncontrolled diabetes with constipation: evidence from the National Health and Nutrition Examination Survey

BACKGROUND

Constipation is highly prevalent in the United States. The association of dietary fat intake with constipation has not been well studied. We recently reported that mice fed a high-fat diet had higher incidence of constipation than regular diet fed mice. The aim of this study was to assess if increased intake of dietary saturated fat in humans is also associated with higher risk of constipation and reduced stool frequency.

METHODS

Analyses were based on data from 6207 adults (≥20 years) from the 2005-2006 and 2007-2008 cycles of the National Health and Nutrition Examination Surveys who had completed the bowel health questionnaire. Constipation was defined as a stool frequency of less than three times per week. Multivariable logistic regression analysis was used to calculate adjusted prevalence odds ratio (OR) estimates. Statistical analyses were performed using R and RStudio softwares.

KEY RESULTS

The prevalence of constipation in this sample was 3.1%. After multivariable adjustment high saturated fat remained associated with constipation. The OR for high saturated fat intake associated with constipation was much higher in diabetics above 65 years, especially in non-Hispanic blacks, females, and those with poor glycemic control, compared to the control group.

CONCLUSIONS & INFERENCES

To the best of our knowledge, this is the first report to investigate the association of high saturated fat diet, bowel frequency, and diabetes. This study demonstrates that a high dietary saturated fat intake is associated with significant increase in the prevalence of constipation, especially in the uncontrolled diabetic, non-Hispanic black, female patients.
