Fast food and anxiety symptoms of Chinese multi-ethnic adolescents: The moderating role of regulatory emotional self-efficacy

BACKGROUND

Although previous studies demonstrated an association between fast food intake and anxiety symptoms in adolescents, this relationship has not been studied in Chinese multi-ethnic adolescents. The purpose of this study is to investigate the aforementioned association and the potential moderating effect of regulatory emotional self-efficacy (RESE) among Chinese multi-ethnic adolescents.

METHODS

A cluster random sampling of 8500 middle school students from 11 counties in Yunnan province was conducted. The Depression Anxiety Stress Scale-21 was utilized to assess anxiety symptoms, while the food frequency questionnaire was employed to gather data on eating behaviors. The association between fast food intake, RESE, and anxiety symptoms was analyzed using generalized linear models. The moderating effect of RESE on the association between fast food intake and anxiety symptoms was examined using structural equation models.

RESULTS

The positive rate of anxiety symptoms in middle school students was 48.5 % (4120/8500). The positive rate of depressive symptoms in females (53.3 %, 2301/4316) was higher than that in males (43.5 %, 1819/4184). Chinese fast food intake (males vs females: β = 0.26, 95%CI:0.14-0.39; β = 0.16, 95%CI:0.02-0.29), expressing positive affect (β = -0.04, 95%CI:-0.07-0.01; β = -0.06, 95%CI:-0.10-0.03) and managing anger/irritation affect (β = -0.11, 95%CI:-0.14-0.08; β = -0.16, 95%CI:-0.19-0.12) was associated with anxiety symptoms in males and females (all P < 0.05). Takeaway fast food intake (β = 0.19, 95%CI:0.02-0.35) and managing despondency/distress affect (β = -0.08, 95%CI:-0.12-0.04, P < 0.001) was associated with anxiety symptoms in females (all P < 0.05). RESE significantly inversely moderated the association between fast food intake and anxiety symptoms (all participants: β = -0.11; males: β = - 0.08; females: β = - 0.14; all P < 0.01).

LIMITATIONS

Association observed in the cross-sectional study is uncertain and need to be confirmed in cohort studies.

CONCLUSION

Our findings suggest that fast food intake may be associated with an increased risk of anxiety symptoms among Chinese multi-ethnic adolescents, while good RESE can potentially mitigate this risk.

Overall diet quality, food groups and mental health disorders among Brazilians older than 15 years old: Brazilian National Health Survey - 2019

BACKGROUND

Adherence to a nutrient-dense diet can have an impact on depression and other mental health issues. Little is known whether this is attributed to some or all components and how these differ in a country that is known to have a vast diversity of nutrient-dense foods. The aim was to examine whether there is a relationship between individual food groups with depression and other mental health disorders.

METHODS

Data was from 89,955 Brazilians from the National Health Survey. Mental health and diet were accessed using a screener questionnaire. Descriptive statistics and regression analyses were calculated.

RESULTS

Persons living with depression had significantly lower diet scores for vegetables/fruits (β = -0.08, 95 % CI -0.13, -0.02), grains/roots (β = -0.05; 95%CI (-0.07, -0.03)), beans (β = -0.03; 95%CI (-0.04, -0.01)) and higher scores for sweetened beverages (β = 0.04; 95%CI (0.01, 0.07)), sweets and sugars (β = 0.03; 95%CI (0.01, 0.05) and high fat/sodium products (β = 0.04; 9%CI (0.01, 0.07). Individuals living with other mental disorders showed lower scores for grains/roots (β = -0.03; 95%CI (-0.06, -0.01)) and higher scores for sweets and sugars (β = 0.06; 95%CI (0.03, 0.09)) and high fat/sodium products (β = 0.05; 95%CI (0.01, 0.09)).

CONCLUSION

People with mental health disorders are more likely to have an unhealthy diet. Relationships were slightly stronger with depression in particular food groups as other mental disorders. Further studies are needed to help in the prevention of these disorders.

Did a workplace sugar-sweetened beverage sales ban reduce anxiety-related sugar-sweetened beverage consumption during the COVID-19 pandemic?

OBJECTIVE

Workplace sugar-sweetened beverage (SSB) sales bans can reduce SSB consumption. Because stress and anxiety can promote sugar consumption, we examined whether anxiety among hospital employees during the COVID-19 pandemic was associated with changes in SSB consumption and explored whether this relationship varied by exposure to a workplace SSB sales ban.

DESIGN

In a prospective, controlled trial of workplace SSB sales bans, we examined self-reported anxiety (generalised anxiety disorder-7) and self-reported SSB consumption (fluid ounces/d) before (July 2019) and during (May 2020) the COVID-19 pandemic.

SETTING

Hospital sites in two conditions (four with SSB sales bans and three without sales bans) in Northern California.

PARTICIPANTS

We sampled 580 participants (hospital employees) from a larger trial of sales bans; all were regular consumers of SSB (minimum 3/week at main trial enrollment). This subsample was chosen based on having appropriately timed data for our study questions.

RESULTS

Across conditions, participants reduced SSB consumption over the study period. However, participants with higher pandemic-era anxiety scores experienced smaller reductions in SSB consumption after 9 months compared with those with lower anxiety scores (β = 0·65, P < 0·05). When the sample was disaggregated by sales ban condition, this relationship held for participants in the control group (access to SSB at work, β = 0·82, P < 0·05), but not for those exposed to an SSB sales ban (β = 0·42, P = 0·25).

CONCLUSIONS

SSB sales bans likely reduce SSB consumption through multiple pathways; buffering stress-related consumption may be one mechanism.

Nutrition-Related Experiences of Women With Perinatal Depression During the COVID-19 Pandemic: A Qualitative Study

Women with perinatal depression are at a high risk for unhealthy dietary behaviors but whether the coronavirus disease 2019 (COVID-19) pandemic has exacerbated this risk is unknown. Here we report the findings of a qualitative study exploring the impact of the COVID-19 pandemic on nutrition-related experiences of women with perinatal depression. Using a qualitative descriptive approach, in-depth interviews were conducted with 18 women with a history of perinatal depression and 10 healthcare providers. A semistructured format elicited how food and nutrition-related behaviors of women with perinatal depression were affected by the COVID-19 pandemic. Thematic analysis identified 4 themes related to the COVID-19 pandemic: (1) Adaptations in shopping and cooking behaviors; (2) increases in stress and declines in respite; (3) declines in support and increases in isolation; and (4) low levels of breastfeeding guidance. Our findings confirm the importance of resilience among women with perinatal depression and future research is needed to elucidate the mechanisms connecting resilience and dietary behaviors.

Effects of physical distancing by COVID-19 pandemic on diet quality, neurological and immunological markers, and fecal microbiota of Brazilian older women

Physical distancing was used to prevent transmission of COVID-19, however there are concerns that this may promote harmful impacts on health, such as reduced levels of physical practice and changes in food intake and gut microbiota composition. This study evaluated the impacts of 6 months physical distancing on Brazilian older women upon body mass index (BMI), strength, physical activity level (IPAQ), eating habits, neurological markers (brain-derived neurotrophic factor-BDNF and cortisol), cytokines (IL-2, IL-5, IL-6, IL-10, interferon-IFN-γ, tumor necrosis factor-TNF-α), aging-associated markers (vascular endothelial growth factor-VEGF, insulin-like growth factor-IGF-1, klotho and thymic stromal lymphopoietin-TSLP), besides specific groups of fecal microbiota. Fifteen women, over 60 years old, residents of São Paulo state (Brazil), were evaluated in March and in September 2020. The older adult women, with a mean age 66 ± 6.2 years presented significantly increased BMI and high effect size for non-protective foods consumption, reduced light physical activity and strength 6 months following the physical distancing. Furthermore, the serum concentration of IFN-γ, IGF-1, and IFN-γ/IL-5 were significantly higher, while lower concentration of IL-2 and IL-5 were observed 6 months after the physical distancing. Significant increase was noted only to Blautia spp. abundance after 6 months of physical distancing. Several correlations were observed at both before and after physical distancing, however, interestingly, many of them were lost or inverted 6 months following, while new ones emerged. Taken together, these results showed that lifestyle changes and stress conditions addressed by physical distancing from the COVID-19 pandemic impacted the health of older women included in the present study. Therefore, future follow-up studies are essential to propose interventions in order to restore the health conditions observed before the pandemic period, and thus to maintain the quality of life of older adults in different socioeconomic contexts.
