The association between diet quality, dietary patterns and depression in adults
Quirk, S.E., Williams, L.J., O’Neil, A. et al. The association between diet quality, dietary patterns and depression in adults: a systematic review. BMC Psychiatry 13, 175 (2013). https://doi.org/10.1186/1471-244X-13-175
Background
Recent evidence suggests that diet modifies key biological factors associated with the development of depression; however, associations between diet quality and depression are not fully understood. We performed a systematic review to evaluate existing evidence regarding the association between diet quality and depression.
Results
Twenty-five studies from nine countries met eligibility criteria. Our best-evidence analyses found limited evidence to support an association between traditional diets (Mediterranean or Norwegian diets) and depression. We also observed a conflicting level of evidence for associations between (i) a traditional Japanese diet and depression, (ii) a “healthy” diet and depression, (iii) a Western diet and depression, and (iv) individuals with depression and the likelihood of eating a less healthy diet.
Conclusion
To our knowledge, this is the first review to synthesize and critically analyze evidence regarding diet quality, dietary patterns and depression. Further studies are urgently required to elucidate whether a true causal association exists.
Depression In Pregnancy
Pregnancy depression affects up to 10% of females, with greater prevalence in poor and middle income nations, and is only slightly lower than postpartum depression. Despite this, only about 20% of pregnant women with depression receive adequate therapy. This is important since depression may have a significant impact on a woman's sense of well-being, relationships, and overall quality of life. Untreated or inadequately treated depression can also have a negative impact on the progeny. Systematic evaluations reveal a rise in newborn morbidity markers such as preterm delivery, childhood emotional issues, behaviour problems, and, in certain cases, poor cognitive development.
