          Abstract

          Resumen Introducción: estudios previos sugieren que un bajo consumo de ácidos grasos poliinsaturados (AGPI) omega-3 y razón omega-6/omega-3 alta, así como niveles séricos bajos, se asocian con trastornos depresivos, sin embargo, los resultados no son concluyentes. Objetivos: evaluar los niveles séricos de AGPI omega-3 (ácido eicosapentaenoico [EPA], docosahexaenoico [DHA], alfalinolenico [ALA]) y la razón omega-6 (ácido araquidónico [AA])/EPA, en relación a los síntomas depresivos en universitarios del norte de México. Material y métodos: estudio transversal que incluyó 60 participantes (18 a 24 años de edad) de ambos sexos, con determinaciones séricas de EPA, DHA, ALA y AA, quienes respondieron la escala de depresión del Centro de Estudios Epidemiológicos (CES-D) validada para estudiantes mexicanos. La relación de los AGPI omega-3 y omega-6 con los síntomas depresivos se evaluó con modelos de regresión lineal. Resultados: los niveles séricos de EPA, DHA y razón EPA/DHA no se correlacionaron con síntomas depresivos, un incremento en ALA sérico se correlacionó con menos síntomas depresivos antes y después de ajustar por confusores; sin embargo, los resultados no fueron estadísticamente significativos. En mujeres, la escala CES-D incrementó 5,5 puntos (p = 0,57) por 1% de incremento en EPA y disminuyó 6,7 puntos (p = 0,39) por 1% de incremento en ALA. Conclusiones: nuestros resultados no confirman la asociación entre los niveles séricos de AGPI omega-3 y razón omega-6/omega-3 con síntomas depresivos. La correlación negativa del nivel sérico de ALA con síntomas depresivos necesita ser confirmada en estudios de seguimiento.

          Abstract Introduction: Previous studies suggest that low consumption as well as low serum levels of polyunsaturated fatty acids (PUFA) omega-3 and a high omega-6/omega-3 ratio may be implicated in the etiology of depressive disorders, however, epidemiologic evidence is inconclusive. Objective: To assess the relationship of serum levels of omega-3 fatty acids (docosahexaenoic [DHA], eicosapentaenoic [EPA], alpha-linolenic fatty acid [ALA]) and the omega-6 (arachidonic acid [AA])/EPA ratio with depressive symptoms among Mexican college students. Material and methods: A cross-sectional study that included 60 male and female participants (ages 18 to 24 years) with serum levels of EPA, DHA, ALA and AA. Depressive symptoms were ascertained with the Center for Epidemiologic Studies Depression (CES-D) scale validated for Mexican students. Linear regression was used to assess the relationship between depressive symptoms and serum PUFA omega-3 and omega-6. Results: Serum levels of EPA, DHA and EPA/DHA ratio were not related to depressive symptoms, high serum ALA was related with lower depressive symptoms before and after covariate adjustment; however, these results were not statistically significant. Among women, 1% increase in EPA resulted in 5.5. (p = 0.57) increase in the depressive scale scores while 1% increase in ALA resulted in 6.7 decrease (p = 0.39) in the scores. Conclusions: Our results did not confirm the relationship of serum levels of PUFA omega-3 and omega-6/omega-3 ratio with depressive symptoms; the negative correlation of serum ALA with depressive symptoms remains to be confirmed in prospective studies.

            Depression in adolescence.

            Unipolar depressive disorder in adolescence is common worldwide but often unrecognised. The incidence, notably in girls, rises sharply after puberty and, by the end of adolescence, the 1 year prevalence rate exceeds 4%. The burden is highest in low-income and middle-income countries. Depression is associated with substantial present and future morbidity, and heightens suicide risk. The strongest risk factors for depression in adolescents are a family history of depression and exposure to psychosocial stress. Inherited risks, developmental factors, sex hormones, and psychosocial adversity interact to increase risk through hormonal factors and associated perturbed neural pathways. Although many similarities between depression in adolescence and depression in adulthood exist, in adolescents the use of antidepressants is of concern and opinions about clinical management are divided. Effective treatments are available, but choices are dependent on depression severity and available resources. Prevention strategies targeted at high-risk groups are promising.

              The costs of depression.

              The data reported herein show clearly that major depression is a commonly occurring and burdensome disorder. The high prevalence, early age of onset, and high persistence of MDD in the many different countries where epidemiologic surveys have been administered confirm the high worldwide importance of depression. Although evidence is not definitive that MDD plays a causal role in its associations with the many adverse outcomes reviewed here, there is clear evidence that depression has causal effects on a number of important mediators, making it difficult to assume anything other than that depression has strong causal effects on many dimensions of burden. These results have been used to argue for the likely cost -effectiveness of expanded depression treatment from a societal perspective. Two separate, large-scale, randomized, workplace depression treatment effectiveness trials have been carried out in the United States to evaluate the cost effectiveness of expanded treatment from an employer perspective. Both trials had positive returns on investment to employers. A substantial expansion of worksite depression care management programs has occurred in the United States subsequent to the publication of these trials. However, the proportion of people with depression who receive treatment remains low in the United States and even lower in other parts of the world. A recent US study found that only about half of workers with MDD received treatment in the year of interview and that fewer than half of treated workers received treatment consistent with published treatment guidelines. Although the treatment rate was higher for more severe cases, even some with severe MDD often failed to receive treatment. The WMH surveys show that treatment rates are even lower in many other developed countries and consistently much lower in developing countries. Less information is available on rates of depression treatment among patients with chronic physical disorders, but available evidence suggests that expanded treatment could be of considerable value. Randomized, controlled trials are needed to expand our understanding of the effects of detection and treatment of depression among people in treatment for chronic physical disorders. In addition, controlled effectiveness trials with long-term follow-ups are needed to increase our understanding of the effects of early MDD treatment interventions on changes in life course role trajectories, role performance, and onset of secondary physical disorders.
