The authors sought to examine the association of vascular nutritional factors and depression in an elderly cohort of depression (currently and recently depressed) and comparison (never depressed) subjects.
Nutrient intake over the past year was assessed in 196 elderly depression and comparison individuals with a Block 1998 food-frequency questionnaire. Nutrient intake, body mass index, and Keys score (a measure of the serum cholesterol-raising capacity of the diet) were determined. Subjects were age 60 and over and were participants in a longitudinal study of major depression. All subjects received psychiatric and medical comorbidity assessments; depression subjects also received psychiatric treatment.
Vascular nutritional factors differed between depression and comparison subjects. The depression group had higher intake of saturated fat and cholesterol, higher body mass indices, lower alcohol intake, and higher Keys score than the comparison group. After controlling for age, sex, education, race, and medical comorbidity, associations remained for cholesterol, alcohol, and Keys score. Depression was found to be associated with overall dietary pattern as defined by total kilocalories, saturated fat, cholesterol, body mass index, polyunsaturated fat, sodium, and alcohol.
This study provides evidence that dietary vascular risk factors differ in individuals with current or prior depression when compared with individuals with no history of depression.
"Numerous studies have investigated the relationship between nutritional factors and mood; however, few have examined depression in the elderly and even fewer of the depression studies have focused on factors known to affect vascular disease. In a previous study, we reported that elderly depressed individuals were more likely than never-depressed comparison subjects to consume a diet high in saturated fat and cholesterol, while having a higher body mass index (BMI) (Payne et al., 2006). "
[Show abstract][Hide abstract] ABSTRACT: Studies indicate that diet may be related to the occurrence of brain lesions. The cross-sectional association between food intake and brain lesion volumes in late-life depression was examined in a cohort of elderly individuals with current or prior depression.
Food intake was assessed in 54 elderly vascular depression subjects (vascular depression defined by presence of hyperintensities on brain MRI) using a Block 1998 food frequency questionnaire. Food and kilocalorie intake were determined. Brain lesion volumes were calculated from MRI. Subjects were aged 60 or over and were participants in a longitudinal study of major depression. All subjects received psychiatric assessment and treatment, and medical comorbidity assessments.
High-fat dairy and whole grains were significantly positively correlated with brain lesion volume, while other food groups were not significantly associated with lesion volume. In multivariable analyses, controlling for age, sex, hypertension, diabetes and total kilocalories, the positive association with lesion volume remained significant for both high-fat dairy and whole grains.
High fat dairy and whole grain consumption may be associated with brain lesions in elderly subjects with depression.

[Show abstract][Hide abstract] ABSTRACT: •
Depression is a significant problem for older adults.
Dietary factors related to either vascular risk or brain health may be important for depression.
Obesity may promote depression.
Inadequate omega-3 fatty acid consumption or levels may be related to depression.
Folate is important for vascular and brain health but its role in depression is unclear.
Brain lesions and their potential dietary etiology may be significant for depression.
[Show abstract][Hide abstract] ABSTRACT: Dispositional optimism has been associated with a lower risk of cardiovascular mortality, but the underlying mechanisms are still largely unknown. We therefore studied whether dispositional optimism was associated with healthy lifestyle and dietary habits.
In 773 (87.1%) of 887 Dutch elderly community-living men with complete data in 1985, the associations of dispositional optimism with lifestyle and dietary factors were assessed at baseline and during follow-up every 5 years up to 15 years using multilevel regression models.
Dispositional optimism was assessed using a four-item questionnaire, and the participants' food consumption was assessed by a cross-check dietary history method that estimates the usual food consumption pattern of the participants. Lifestyle factors were assessed by questionnaires, while weight and height were measured to calculate body mass index.
A high level of dispositional optimism was associated with more physical activity (P<.001), nonsmoking (P=.02), and higher intakes of alcohol (P=.046), fruit (P=.01), vegetables (P=.01), and whole-grain bread (P=.01), independently from age, education, living arrangement, self-rated health, cardiovascular disease, diabetes mellitus, cancer, and body mass index, as well as total energy intake (for dietary factors).
Dispositional optimism in elderly men is associated with healthy lifestyle and dietary habits. A low level of optimism may indirectly affect proneness to cardiovascular death via unhealthy behavioral choices.
