Participants completed a computer-based cognition testing battery (IntegNeuro™) evaluating the domains of impulsivity, attention, information processing, memory and executive function. The Omega-3 Index (O3I) was used to determine n-3 PUFA status (percentage of EPA (20:5n-3) plus DHA (22:6n3) in the red cell membrane) and the participants were divided into O3I tertile groups: T1 < 5.47%, T2 = 5.47–6.75%, T3 > 6.75%. Potential confounding factors of BMI, inflammatory status (C-reactive Protein), physical activity (total MET-min/wk), alpha1-acid glycoprotein, serum ferritin and hemoglobin, were assessed. Data reported as z-scores (mean ± SD), analyses via ANOVA and ANCOVA. Results: Two hundred ninety-nine women (26.9 ± 5.4 y) completed the study (O3I data, n = 288). The ANOVA showed no overall group differences but a significant group × cognition domain interaction (p < 0.01). Post hoc tests showed that participants in the low O3I tertile group scored significantly lower on attention than the middle group (p = 0.01; ES = 0.45 [0.15–0.74]), while the difference with the high group was borderline significant (p = 0.052; ES = 0.38 [0.09–0.68]). After confounder adjustments, the low group had lower attention scores than both the middle (p = 0.01) and high (p = 0.048) groups. These findings were supported by univariate analyses which found significant group differences for the attention domain only (p = 0.004). Conclusions: Cognitive function in the attention domain was lower in women with lower O3I, but still within normal range. This reduced but normal level of cognition potentially provides a lower baseline from which cognition would decline with age. Further investigation of individuals with low n-3 PUFA status is warranted.]]> Wed 04 Aug 2021 18:23:51 AEST ]]> Relationship between obesity and cognitive function in young women: the food, mood and mind study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30746 Wed 02 Mar 2022 14:27:26 AEDT ]]> Iron deficiency anemia, not iron deficiency, is associated with reduced attention in healthy young women https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31008 30 kg/m 2 ). Participants completed a validated, computer-based cognition assessment evaluating impulsivity, attention, information processing, memory and executive function; CF reported as z-scores (mean ± SD). Iron status and CF were compared between groups via ANOVA, with adjustment for potential confounders (BMI, physical activity, C-reactive protein) via ANCOVA. A total of 157 NW and 142 OB women (25.8 ± 5.1 years) participated. Prevalence of ID and IDA were 14% and 6% respectively, with no significant difference between NW and OB groups. Women with IDA scored significantly lower on attention (although within normal range; ±1 z-score), compared to ID (IDA: -0.75 ± 1.89; ID: 0.53 ± 1.37; p = 0.004) but not IR (0.03 ± 1.33, p = 0.21) groups; there were no significant differences between ID and IR groups (p = 0.34). Adjustment for confounders did not significantly alter these results. In conclusion, women with IDA showed significantly reduced attention compared to women with ID.]]> Thu 27 Jan 2022 15:59:35 AEDT ]]> Effect of aerobic exercise training dose on liver fat and visceral adiposity https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28075 2peak, 60 min, 4 d/week); ii) high intensity, low volume aerobic exercise (HI:LO, 70% VO2peak, 45 min, 3 d/week); iii) low to moderate intensity, low volume aerobic exercise (LO:LO, 50% VO2peak 45 min, 3 d/week); or iv) placebo (PLA). Liver fat (spectroscopy) and VAT (magnetic resonance imaging) were measured before and after intervention. Results: Forty-seven of the 48 (n = 12 in each group) participants completed the trial. There were no serious adverse events. There was a significant change in group x time interaction in liver fat, which reduced in HI:LO by 2.38 ± 0.73%, in LO:HI by 2.62 ± 1.00%, and in LO:LO by 0.84 ± 0.47% but not in PLA (increase of 1.10 ± 0.62%) (p = 0.04). There was a significant reduction in VAT in HI:LO (-258.38 ± 87.78 cm3), in LO:HI (-386.80 ± 119.5 cm3), and in LO:LO (-212.96 ± 105.54 cm3), but not in PLA (92.64 ± 83.46 cm3) (p = 0.03). There were no significant differences between the dose or intensity of the exercise regimen and reductions in liver fat or VAT (p >0.05). Conclusion: The study found no difference in efficacy of liver fat reduction by either aerobic exercise dose or intensity. All of the aerobic exercise regimens employed reduced liver fat and VAT by a small amount without clinically significant weight loss.]]> Sat 24 Mar 2018 07:39:45 AEDT ]]> Efficacy of the omega-3 index in predicting non-alcoholic fatty liver disease in overweight and obese adults: a pilot study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26621 Sat 24 Mar 2018 07:34:00 AEDT ]]> Association between obesity and omega-3 status in healthy young women https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38154 Mon 29 Jan 2024 17:46:57 AEDT ]]> Effect of fish oil supplementation on hepatic and visceral fat in overweight men: a randomized controlled trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35703 94 cm) were randomly allocated to consume fish oil (total daily dose: 1728 mg marine triglycerides, of which 588 mg EPA and 412 mg DHA, combined with 200 mg antioxidant, coenzyme Q10) or placebo (olive oil capsules) daily for 12 weeks. Liver fat was assessed using proton magnetic resonance spectroscopy. All outcomes were assessed at baseline and following 6 and 12 weeks of supplementation. Baseline liver fat was 4.6 ± 0.5% (range: 0.6 to 18.2%); 16 (32%) participants met the criteria for NAFLD (>5.5% liver fat). Repeated measures ANOVA revealed no significant time or group × time effect for fish oil versus placebo for liver fat, liver enzymes, anthropometry, or body composition including VAT (p > 0.05 for all), with similar finding for sub-analysis of participants with NAFLD. Omega-3 PUFA did not appear to be an effective agent for reducing liver fat in overweight men. The factors determining the health benefits of omega-3 PUFA supplementation on an individual level need to be clarified.]]> Fri 03 Dec 2021 10:33:51 AEDT ]]> Effect of resistance training on liver fat and visceral adiposity in adults with obesity: a randomized controlled trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30121 Fri 03 Dec 2021 10:32:25 AEDT ]]>
