Very first, brand new mountain of your own dating BP which have Na consumption ranged by the time consumption, recommending you to definitely Na density can get reflect the partnership that have BP finest than just pure Na intake do
There was a significant 3-way interaction between Na intake, energy, and obesity status for SBP (P=0.033); for DBP, the 3-way interaction was not significant, but there was a significant interaction between energy intake and obesity (P=0.005). In stratified models, the association of Na with SBP was stronger at lower energy intake (higher Na density) than at higher energy intake (lower Na density) in both nonobese (interaction of Na with energy; P<0.001) and obese (interaction of Na with energy; P=0.028); the association of Na and DBP by energy intakes was similar (interaction of Na with energy, P=0.005 nonobese; P=0.049 obese). On the control diet at 2300 mg Na intake in the nonobese, SBP was 4.7 mm Hg (95% CI, 1.0, 8.5) higher at 2100 kcal compared with 3200 kcal (Figure 3A), and DBP was 3.1 mm Hg (95% CI, 0.7, 5.5) higher (Figure 3C). In obese at 2300 mg Na intake on the control diet, there were no differences in SBP (0.6 mm Hg; 95% CI, ?3.8 to 4.9; Figure 3B) or DBP (1.8 mm Hg; 95% CI, ?1.0 to 4.5; Figure 3D) between 2100 and 3200 kcal. On the DASH diet at 2300 mg Na, there were no significant differences in SBP at 2100 versus 3200 kcal regardless of obesity status (2.5 mm Hg; 95% CI, ?1.0 to 6.0 for nonobese and datingranking.net/chatki-review ?1.3 mm Hg; 95% CI, ?6.0 to 3.4 for obese). On the DASH diet at 2300 mg Na, DBP was higher at 2100 versus 3200 kcal in the nonobese (2.1 mm Hg; 95% CI, 0.1–4.4), but not in the obese (?0.3 mm Hg (95% CI, ?3.2 to 2.6).
Figure 3. Interaction of absolute Na intake and energy intake on blood pressure at 3 energy levels stratified by obesity status, indicating 3 levels of Na density (L, I, and H), among normal and overweight (body mass index [BMI] <30 kg/m 2 , A and C) and obese (BMI?30 kg/m 2 , B and D) participants on the control diet. The vertical line is drawn at 2300 mg absolute Na intake. Error bars represent ±1 SE. Results from mixed-effects models of continuous Na and energy, adjusted for age, sex, race, smoking, cohort, diet type (DASH [Dietary Approaches to Stop Hypertension] or control), clinical center, and carryover effects stratified by obesity status. DBP indicates diastolic blood pressure; and SBP, systolic blood pressure.
That it studies try used to decide if the matchmaking between Na and you can BP may differ which have times consumption. Several key conclusions came up. Second, since the prior to now said, the result away from Na cures is actually attenuated regarding setting away from the brand new Dash diet plan compared to the new manage diet plan, recommending that regions of eating plan including dictate the latest BP response to changes in Na consumption. 5,a dozen,13 And attenuating brand new BP reaction to Na, the Dash diet as well as lower BP, in keeping with proof one areas of eating plan, including a heightened intake of potassium, alone lower BP. fourteen Third, the new relationship out-of Na having opportunity consumption with the BP continuous when the fresh analyses was indeed stratified of the race, except for DBP certainly one of whites. Next, having stratification from the obesity status, larger differences in BP of the opportunity intake were observed those types of who were nonobese weighed against obese.
Whilst the Dashboard–Na data regulated Na density, rather than pure Na consumption, the initial consequence of so it trial had been translated in terms of Na consumption instead of Na occurrence. Having less revealing overall performance by Na occurrence get echo the lack of study for the energy consumption in lot of knowledge. Analysis of the relationships from Na thickness which have death from inside the observational studies have given blended efficiency. The investigation out-of Na thickness which have death on NHANES II follow-right up study (National Health insurance and Nourishment Examination Questionnaire) and you will from NHANES III recommended an enthusiastic inverse connection out of Na and cardiovascular illnesses mortality, even if given Na regarding opportunity consumption. fifteen,sixteen On these degree, however, Na and effort consumption was indeed estimated using one twenty four-hours recall, that’s not enough to estimate one’s typical diet intake because of high go out-to-date version in Na consumption and effort intake as well as their ratio. After that, time consumption is actually implausibly lower in each other training. You’ll be able to that seen relationship anywhere between Na intake and you may heart disease mortality can be said of the significantly less than-reporting bias, that’s, in the event that over weight people report straight down Na occurrence and are also likely to be in order to die of cardiovascular disease, the fresh new noticed relationship get echo the impact from obesity unlike eating plan. The most recent facts out of a prospective cohort studies (n=716, 19-season follow-up) aligns towards the outcome of the current studies, having reported incidence from aerobic incidents twice as higher one particular in the highest instead of reduced quartile out of Na thickness (22% instead of eleven%, respectively; P=0.005) based on eight-time restaurants facts compiled from the baseline. 17
