Association of Dietary and Lifestyle Inflammation Score With Cardiorespiratory Fitness

Abstract

ObjectiveWe aimed to assess the potential association of dietary (DIS) and lifestyle inflammation score (LIS) and their joint association (DLIS) with cardiorespiratory fitness (CRF) in Tehranian adults.DesignThe present study was designed cross-sectional.ParticipantsA total of 265 males and females aged 18–70 years (mean ± SD: 36.9 ± 13.3) were entered in the present cross-sectional study. Eligible participants were healthy men and women who were free of medications and had no acute or chronic infection or inflammatory disease.MeasuresThe DIS was calculated by the use of data from 18 anti- and pro-inflammatory dietary components, and the LIS by three non-dietary components including physical activity, smoking status, and general adiposity, with higher scores indicating a more pro-inflammatory diet and lifestyle, respectively. The DLIS was calculated by summing the DIS and LIS. CRF was assessed by the Bruce protocol and VO2 max was measuredas the main variable of CRF. The odds ratio (OR) and 95% confidence interval (CI) of CRF across tertiles of the DIS, LIS, and DLIS were estimated by logistic regression analysis with considering age, gender, energy intake, marital and education status, and occupation as confounders.ResultsThe DLIS ranged from −2.10 to 0.38 (mean ± SD: −1.25 ± 0.64). In the model that controlled for all variables, the ORs of CRF for the second and third tertiles of the DLIS as compared to the first tertile were 0.42 (95%CI: 0.20, 0.90) and 0.12 (95%CI: 0.05, 0.32), respectively (P-trend < 0.001). There was a strong inverse association between the LIS and CRF (ORthirdvs.firsttertile: 0.12, 95%CI: 0.05, 0.32). There was no association between DIS and CRF.ConclusionThe present study examined the joint association of inflammation-related lifestyle behaviors with CRF and found a strong inverse association between a pro-inflammatory lifestyle with CRF. We did not find any association between dietary inflammatory properties with CRF. Future studies should address the relationship between the inflammatory potential of the diet and CRF.

Dietary patterns in rural and metropolitan Australia: a cross-sectional study exploring dietary patterns, inflammation and association with cardiovascular disease risk factors

“…For everyone in the sample, the factor loading of each food group was multiplied by the mean consumption of each food group (in grams per day) to calculate factor scores for each dietary pattern. Adherence to dietary pattern was determined by splitting individual factor scores into quartiles, consistent with previous studies 20 30 31. For example, for a given dietary pattern, participants with a factor score in the top 25% were categorised as high adherers, whereas individuals with a factor score in the lowest 25% were categorised as low adherers 20 30 31.…”

The adherence of a participant to any given dietary pattern did not preclude the participant from being a high or low adherer to any other dietary pattern.…”

“…Our findings are similar to another study in a healthy population that found no association between the DIS and cardiorespiratory fitness. 30 A major difference may also be that the DIS components were derived and validated with data from a food frequency questionnaire, that assesses diet over an extended period, whereas the AHS used a 24-hour dietary recall to assess diet, which collects information on dietary intake over the previous 24 hours. 22…”

A Functional Drink Containing Kaempferia parviflora Extract Increases Cardiorespiratory Fitness and Physical Flexibility in Adult Volunteers

“…Recent studies have demonstrated that oxidative stress and inflammation can disturb physical fitness [ 11 , 12 ]. They can induce tissue injury leading to the poor function of tissues, resulting in reductions in cardiorespiratory fitness, range of motion, particularly around the joints, or flexibility, muscle strength, and endurance; thus, the applications of substances possessing antioxidant and anti-inflammatory effects, such as herbal extracts, as the functional ingredients for developing functional drinks have been the main area of focus.…”
