“…The size of change attributable to the intervention was smaller than is typically considered clinically significant, 44,45 but may nonetheless be important at the population level. 47 Previous studies that found larger effects were focused on overweight and obese participants. 414,17,18 and individuals with pre-existing coronary heart disease.…”

Background Intensive dietary intervention programs may lead to benefits in vitality and other components of health quality. The Women’s Health Initiative (WHI) Dietary Modification (DM) intervention includes a large randomized controlled trial of an intensive intervention. Objective To evaluate whether the intervention is associated with improved health-related quality of life (HRQoL) subscales, overall self-reported health, depressive symptoms, cognitive functioning, and sleep quality. Design Randomized controlled trial was analyzed as intent to treat. Participants Between 1993 and 1998, 48,835 women aged 50 to 79 years were recruited by 40 clinical centers across the United States. Eligibility included having fat intake at baseline ≥32% of total calories, and excluded women with any prior colorectal or breast cancer, recent other cancers, type-1 diabetes, medical conditions with predicted survival less than three years. Intervention Goals were to reduce calories from fat to 20%, increase vegetables and fruit to 5+ servings and increase grain servings to 6+ servings a day. During the first year, 18 group sessions were held, with quarterly sessions thereafter. Main Outcome Measures RAND 36-Item Health Survey was used to assess HRQoL at baseline, year 1, and close-out (about 8 years post randomization), and estimate differential HRQoL subscale change scores. Statistical analysis performed Mean change in HRQoL scores (year 1 minus baseline) were compared by randomization group using linear models. Results At one year, there was a differential change between intervention and comparison group of 1.7 units (1.5, 2.0) in general health associated with the intervention. DM intervention improved physical functioning by 2.0 units (1.7, 2.3), vitality by 1.9 units (1.6, 2.2), and global QOL by 0.09 units (0.07, 0.12). With the exception of global QOL, these effects were significantly modified by BMI at baseline. Conclusions DM intervention was associated with small, but significant improvements in three health related quality of life subscales: general health, physical functioning, and vitality at one year follow-up, with the largest improvements seen in the women with the greatest baseline BMI.

“…Of those studies that exist, the majority have (i) investigated the effect of FV on psychological well-being as a secondary outcome and (ii) investigated the effect of FV modification in conjunction with other dietary or lifestyle changes. Despite this, four dietary interventions have focused more specifically, or have carried out additional analysis, on FV and psychological health (92)(93)(94)(95) . The majority of these have reported heterogeneous findings (92,93,95) .…”

“…Despite this, four dietary interventions have focused more specifically, or have carried out additional analysis, on FV and psychological health (92)(93)(94)(95) . The majority of these have reported heterogeneous findings (92,93,95) . For example, Plaisted et al (92) found that although an FV-rich diet was associated with improved vitality in hypertensive participants over 11 weeks, there were no significant differences when compared with an FV-rich, low-fat dairy diet group or a control group.…”

“…Furthermore, the FV-rich diet was not associated with any improvements in overall mental health. Another study (93) examined the effect of two multi-component lifestyle interventions v. an advice only intervention on the health-related quality of life of pre-hypertensive/ stage one hypertensive participants over 18 months. The results showed that adherence to blood pressure control guidelines (including increased FV intake) and adherence to the same guidelines, plus a dietary approaches to stop hypertension diet, resulted in improvements in vitality, but not general mental health when compared with the advice only group.…”

The potential role of fruit and vegetables in aspects of psychological well-being: a review of the literature and future directions

The objective of the present paper was to review the literature investigating the potential relationship between fruit and vegetables (FV) and psychological well-being. The rising prevalence of mental ill health is causing considerable societal burden. Inexpensive and effective strategies are therefore required to improve the psychological well-being of the population, and to reduce the negative impact of mental health problems. A growing body of literature suggests that dietary intake may have the potential to influence psychological well-being. For example, studies have suggested that particular dietary constituents, including vitamins and minerals, might be beneficial to psychological health. However, in order to better reflect normal dietary intake, health-based research has increasingly begun to focus on whole foods and dietary patterns, rather than individual nutrients. One food group that has received increasing attention with regard to psychological health is FV. This is probably a result of the strong evidence base, which exists in relation to their protective association with a number of chronic diseases, as well as the fact that they are a rich source of some of the nutrients which have been linked to psychological health. While some promising findings exist with regards to FV intake and psychological well-being, overall, results are inconsistent. Possible reasons for this, such as methodological issues related to study design and the measurement of psychological well-being and FV intake, are discussed within this review. Based on the predominantly observational nature of existing literature, the present paper concludes that future well-designed randomised controlled trials are required to investigate the relationship further.

“…In more recent behavioral weight loss trials (the Diabetes Prevention Program [DPP] [19], Look AHEAD [20], and PREMIER [21]), physical HRQOL improved more in the active intervention arms than in the control arms, with no significant between-arm differences in mental HRQOL change, and a small advantage for the active intervention arm in improved depression symptoms.…”

Purpose To evaluate effects of two behavioral weight loss interventions (in-person, remote) on health-related quality of life (HRQOL) compared to a control intervention. Methods 415 obese US adults with at least one cardiovascular risk factor completed five measures of HRQOL and depression: MOS SF-12 physical component summary [PCS] and mental component summary [MCS]; EuroQoL 5-Dimensions [EQ-5D] single index and visual analog scale; PHQ-8 depression symptoms, and PSQI sleep quality scores at baseline and 6 and 24 months after randomization. Change in each outcome was analyzed using outcome-specific mixed effects models controlling for participant demographic characteristics. Results PCS-12 scores over 24 months improved more among participants in the in-person active intervention arm than among control arm participants (P<0.05, ES = 0.21); there were no other statistically significant treatment arm differences in HRQOL change. Greater weight loss was associated with improvements in most outcomes (P<0.05 to <0.0001). Conclusions Participants in the in-person active intervention improved more in physical function HRQOL than participants in the control arm did. Greater weight loss during the study was associated with greater improvement in all PRO except for sleep quality, suggesting that weight loss is a key factor in improving HRQOL.
