Abstract

Depressive symptoms are independently associated with an increased risk of cardiovascular disease (CVD) among individuals with non-diagnosed CVD. The mechanisms underlying this association, however, remain unclear. Inflammation has been indicated as a possible mechanistic link between depression and CVD. This study evaluated the association between persistent depressive symptoms and the onset of low-grade inflammation. From a database of 1,508 young (mean age: 41 years) individuals with no CVD diagnosis who underwent at least two routine health evaluations, 134 had persistent depressive symptoms (Beck Depression Inventory - BDI ≥ 10, BDI+) and 1,374 had negative symptoms at both time points (BDI-). All participants had been submitted to repeated clinical and laboratory evaluations at a regular follow-up with an average of 26 months from baseline. Low-grade inflammation was defined as plasma high-sensitivity C-Reactive Protein (CRP) concentrations > 3 mg/L. The outcome was the incidence of low-grade inflammation evaluated by the time of the second clinical evaluation. The incidence of low-grade inflammation was more frequently observed in the BDI+ group compared to the BDI- group (20.9% vs. 11.4%; p = 0.001). After adjusting for sex, age, waist circumference, body mass index, levels of physical activity, smoking, and prevalence of metabolic syndrome, persistent depressive symptoms remained an independent predictor of low-grade inflammation onset (OR = 1.76; 95% CI: 1.03-3.02; p = 0.04). Persistent depressive symptoms were independently associated with low-grade inflammation onset among healthy individuals. Sintomas depressivos estão associados de forma independente ao risco aumentado de doença cardiovascular (DCV) em indivíduos com DCV não diagnosticada. Os mecanismos subjacentes a essa associação, entretanto, não estão claros. Inflamação tem sido indicada como um possível elo mecanicista entre depressão e DCV. Este estudo avaliou a associação entre sintomas depressivos persistentes e o início de inflamação de baixo grau. De um banco de dados de 1.508 indivíduos jovens (idade média: 41 anos) sem diagnóstico de DCV submetidos a pelo menos duas avaliações de saúde de rotina, 134 tinham sintomas depressivos persistentes (Inventário de Depressão de Beck - BDI ≥10, BDI+) e 1.374 não apresentavam sintomas em nenhuma das ocasiões (BDI-). Todos os participantes foram submetidos a repetidas avaliações clínicas e laboratoriais em seguimento regular, cuja média foi de 26 meses desde a condição basal. Definiu-se inflamação de baixo grau como concentração plasmática de proteína C reativa (PCR) ultrassensível > 3 mg/L. O desfecho foi a incidência de inflamação de baixo grau por ocasião da segunda avaliação clínica. A incidência de inflamação de baixo grau foi maior no grupo BDI+ em comparação ao grupo BDI- (20,9% vs. 11,4%; p = 0,001). Após ajuste para sexo, idade, circunferência abdominal, índice de massa corporal, níveis de atividade física, tabagismo e prevalência de síndrome metabólica, os sintomas depressivos persistentes continuaram sendo um preditor independente de início de inflamação de baixo grau (OR = 1,76; IC 95%: 1,03-3,02; p = 0,04). Sintomas depressivos persistentes foram independentemente associados com início de inflamação de baixo grau em indivíduos saudáveis.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 August 2017.
All research outputs
#14,283,318
of 25,382,440 outputs
Outputs from Arquivos Brasileiros de Cardiologia
#289
of 1,210 outputs
Outputs of similar age
#155,866
of 328,273 outputs
Outputs of similar age from Arquivos Brasileiros de Cardiologia
#3
of 20 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,210 research outputs from this source. They receive a mean Attention Score of 4.0. This one has done well, scoring higher than 75% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 328,273 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 85% of its contemporaries.
