Objective: This study examined adherence to dietary guidelines and symptoms of sleep problems (e.g. taking a long time to fall sleep or waking up early) and their associations in a sample of older Australian women (68-73 years of age).
Design: This was a population-based cross-sectional study. Adherence to the dietary guidelines was measured using a validated FFQ and reported as a diet quality score. Symptoms of sleep problems were measured using five questions and a total score was derived. Multivariate linear regression was used to investigate the association between these outcomes, adjusted for the potential confounding influence of demographic (i.e. age and marital status) and lifestyle (i.e. physical activity, stress, alcohol intake, sleep medication use) variables.
Setting: Respondents from the 1946-1951 cohort of the Australian Longitudinal Study on Women's Health who completed Survey 9 were included.
Participants: Data from 7956 older women (mean age ± sd: 70·8 ± 1·5) were included.
Results: 70·2 % reported having at least one symptom and 20·5 % had between 3 and 5 symptoms of sleep problems (mean score ± sd: 1·4 ± 1·4, range 0-5). Adherence to dietary guidelines was poor with an average diet quality score of 56·9 ± 10·7 (range 0-100). Better adherence to dietary guidelines was associated with fewer sleep problem symptoms (: -0·065, 95 % CI: -0·012, -0·005) and remained significant after adjusting for confounding influences.
Conclusions: These findings support the evidence that adherence to dietary guidelines is associated with symptoms of sleep problems in older women.

Assessing the impact of magnesium-based nutritional education on lipid profiles in individuals with type 2 diabetes mellitus: a quasi-experimental study.

Department of Clinical Nutrition, Faculty of Applied Medical Sciences, King Abdulaziz University, Jeddah, Saudi Arabia.
Background: The potential therapeutic role of magnesium (Mg) in type 2 diabetes mellitus (T2DM) remains insufficiently studied despite its known involvement in critical processes like lipid metabolism and insulin sensitivity. This study examines the impact of Mg-focused nutritional education on lipid profile parameters, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in T2DM patients.
Methods: Thirty participants with T2DM were recruited for this within-subject experimental study.
Associations of healthy lifestyle and family income to poverty ratio with all-cause mortality among people with prediabetes and diabetes: a prospective cohort study.

Background: Family income to poverty ratio (PIR) may have independent effects on diet and lifestyle factors and the development of prediabetes and diabetes, as well as on mortality. It is unclear how the protective effect of a healthy lifestyle against death differs between individuals with different glucose metabolic profiles and whether PIR mediates this effect. This study aimed to explore whether healthy lifestyle and family PIR reduced the risk of all-cause mortality in participants with different metabolic status and the mediating role of PIR.

Purpose Of Review: This review examines the long-term efficacy and safety of various nutritional and pharmacological strategies for managing obesity. The focus is on the Mediterranean diet (MedDiet), very low-energy ketogenic therapy (VLEKT), and pharmacological interventions such as naltrexone/bupropion and liraglutide. Given the chronic nature of obesity, understanding the sustainability and impact of these treatments over time is critical.
