There is scientific evidence on the protective effects of nut intake against cognitive decline in the elderly; however, this effect has been less explored in child neurodevelopment and no studies ...have explored the potential longitudinal association with nut intake during pregnancy. We aimed to analyze the association of maternal nut intake during pregnancy with child neuropsychological outcomes. We included 2208 mother–child pairs from a population-based birth cohort in four regions of Spain. The follow up settings were during pregnancy (first and third trimesters), birth, 1.5, 5 and 8 years. Neuropsychological examinations were based on Bayley Scales of Infant Development (1.5 years), McCarthy scales of Children’s Abilities (5 year), Attention Network Test (ANT, 8 year) and N-Back test (8 year). Nut intake in pregnancy was reported through a validated food frequency questionnaire during the first and the third trimester. Multivariable regressions analyzed associations after controlling for priori selected confounders notably maternal education, social class, body mass index, energy intake, fish intake, omega-3 supplements, alcohol consumption and smoking habits during pregnancy. Children within the highest tertile of maternal nut consumption during first pregnancy trimester (> 32 g/week) had a decrease of 13.82 ms 95% confidence interval (CI) - 23.40, - 4.23 in the ANT—hit reaction time standard error, compared to the first tertile (median 0 g/w). A similar protective association pattern was observed with the other cognitive scores at the different child ages. After correcting for multiple testing using Bonferroni familywise error rate (FWER), Hochberg FWER and Simes false discovery rate, ANT—hit reaction time standard error remained significant. Final model estimates by inverse probability weighting did not change results. Third pregnancy trimester nut intake showed weaker associations. These data indicate that nut intake during early pregnancy is associated with long-term child neuropsychological development. Future cohort studies and randomized clinical trials are needed to confirm this association pattern in order to further extend nutrition guidelines among pregnant women.
Purpose
Previous studies show that consuming foods preserved by salting increases the risk of gastric cancer, while results on the association between total salt or added salt and gastric cancer are ...less consistent and vary with the exposure considered. This study aimed to quantify the association between dietary salt exposure and gastric cancer, using an individual participant data meta-analysis of studies participating in the Stomach cancer Pooling (StoP) Project.
Methods
Data from 25 studies (10,283 cases and 24,643 controls) from the StoP Project with information on salt taste preference (tasteless, normal, salty), use of table salt (never, sometimes, always), total sodium intake (tertiles of grams/day), and high-salt and salt-preserved foods intake (tertiles of grams/day) were used. A two-stage approach based on random-effects models was used to pool study-specific adjusted (sex, age, and gastric cancer risk factors) odds ratios (aORs), and the corresponding 95% confidence intervals (95% CI).
Results
Gastric cancer risk was higher for salty taste preference (aOR 1.59, 95% CI 1.25–2.03), always using table salt (aOR 1.33, 95% CI 1.16–1.54), and for the highest tertile of high-salt and salt-preserved foods intake (aOR 1.24, 95% CI 1.01–1.51)
vs.
the lowest tertile. No significant association was observed for the highest
vs.
the lowest tertile of total sodium intake (aOR 1.08, 95% CI 0.82–1.43). The results obtained were consistent across anatomic sites, strata of
Helicobacter pylori
infection, and sociodemographic, lifestyle and study characteristics.
Conclusion
Salty taste preference, always using table salt, and a greater high-salt and salt-preserved foods intake increased the risk of gastric cancer, though the association was less robust with total sodium intake.
The consumption of sugar-containing beverages (SCB) has been associated with obesity although the evidence in preschool children is scarce. Cross-sectional analyses were performed to assess the ...association between obesity and SCB consumption (packaged juices and sugar-sweetened soft drinks) in 1823 children at the age of 4-5 years from the INfancia y Medio Ambiente (INMA) Project. One drink was defined as a glass of 175 mL, and the consumption of SCB was categorized in <1, 1-7 drinks/week and > 1 drink/day. We used multiple logistic regression to estimate odds ratios (OR). The average SCB consumption was 79.1 mL/day, mainly from packaged juices (80.9%). The SCB consumption was lower in non-obese children than in children with obesity, 76.6 vs 118.4 mL/day (
= 0.02). After adjusting for covariates, children who consumed >1 drink/day showed elevated odds of obesity, OR = 3.23 (95% confidence interval (CI): 1.48-6.98) compared to children who consumed <1 SCB drink a week. Each additional SCB drink per day was associated with higher odds of obesity, OR = 1.55 (1.14-2.09). Higher consumption of packaged juices, but not sugar-sweetened soft drinks, was significantly associated with higher odds of obesity, OR = 1.55 (1.09-2.15) and OR = 1.59 (0.76-3.39), respectively. A higher SCB consumption is associated with obesity in preschool children, mainly due to the consumption of packaged juices.
Inorganic arsenic (i-As) has been related to wide-ranging health effects in children, leading to lifelong concerns. Proportionally, dietary i-As exposure dominates in regions with low arsenic ...drinking water. This study aims to investigate the relation between rice and seafood consumption and urinary arsenic species during childhood and to assess the proportion of urinary i-As metabolites. Urinary arsenic species concentration in 400 4-year-old children living in four geographical areas of Spain, in addition to repeated measures from 100 children at 7 years of age are included in this study. Rice and seafood products intake was collected from children's parents using a validated food frequency questionnaire (FFQ). At 4 years of age, children's urine i-As and monomethylarsonic acid (MMA) concentrations increased with rice product consumption (p-value = 0.010 and 0.018, respectively), and urinary arsenobetaine (AsB) with seafood consumption (p = 0.002). Four-year-old children had a higher consumption of both rice and seafood per body weight and a higher urinary %MMA (p-value = 0.001) and lower % dimethylarsinic acid (DMA) (p-value = 0.017). This study suggests increased dietary i-As exposure related to rice product consumption among children living in Spain, and the younger ones may be especially vulnerable to the health impacts of this exposure also considering that they might have a lower i-As methylation capacity than older children. In contrast, seafood consumption did not appear to influence the presence of potentially toxic arsenic species in this population of children.
•Rice and seafood consumption per body weight was higher for younger children.•Urinary inorganic arsenic metabolites increased with children's rice consumption.•Children's seafood intake was associated with an increase of urinary arsenobetaine.•Older children suggested higher inorganic arsenic methylation capacity.
Objective: Despite the alarming increase in the prevalence of obesity, epidemiologic studies that prospectively examine the fruit and vegetable consumption and other lifestyle factors in relation to ...weight gain (WG) are still insufficient. We explored the associations between fruit and vegetable intake and WG over a 10‐year period in an adult Mediterranean population.
Methods and Procedures: We performed a 10‐year follow‐up study with healthy participants (n = 206) aged 15–80 years at baseline in 1994, who participated in a nutrition survey in Valencia, Spain. Data on diet, lifestyle factors, and body weight were obtained in 1994 and 2004 using a food frequency questionnaire (FFQ) and direct measurements.
Results: The average WG over the study period was 3.41 (s.d. 6.9) kg. In multivariate analyses, participants in the third quartile of fruit intake at baseline in 1994 had lower risk of WG≥3.41 kg compared to those in the lowest quartile (oddsratio (OR) = 0.31, 95% confidence interval (CI), 0.11–0.85; P trend = 0.044). Regarding vegetable intake, the risk of WG was lowest in participants of the fourth quartile (>333 g/day), which had an 84% reduced risk of gaining 3.41 kg weight (OR = 0.18, 95% CI, 0.05–0.66; P trend = 0.017). When the intake of fruits and vegetables was combined, the risk of WG decreased across quartiles, with the lowest risk among those in the fourth quartile (OR = 0.22, 95% CI, 0.06–0.81; P trend = 0.022). Further adjustment for an increased intake of fruits and vegetables over the past 10 years reported by participants in 2004 did not appreciably alter the observed ORs.
Discussion: Dietary patterns associated with a high intake of fruits and vegetables in Mediterranean populations may reduce long‐term risk of subsequent WG and obesity among adults.
The association between sleep and stress and cancer is underinvestigated. We evaluated these factors in association with gastric cancer (GC). Five case-control studies from the Stomach Cancer Pooling ...(StoP) Project were included. We calculated the odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for sleep duration and stress level in association with GC through multiple logistic regression models adjusted for several lifestyle factors. The analysis included 1293 cases and 4439 controls, 215 cardia and 919 noncardia GC, and 353 diffuse and 619 intestinal types. Sleep duration of ≥9 h was associated with GC (OR =1.57, 95% CI = 1.23–2.00) compared to 8 h. This was confirmed when stratifying by subsite (noncardia OR = 1.59, 95% CI = 1.22–2.08, and cardia OR = 1.63, 95% CI = 0.97–2.72) and histological type (diffuse OR = 1.65, 95% CI = 1.14–2.40 and intestinal OR = 1.24, 95% CI = 0.91–1.67). Stress was associated with GC (OR = 1.33, 95% CI = 1.18–1.50, continuous). This relationship was selectively related to noncardia GC (OR = 1.28, 95% 1.12–1.46, continuous). The risk of diffuse (OR = 1.32, 95% CI = 1.11–1.58) and intestinal type (OR = 1.23, 95% CI = 1.07–1.42) were higher when stress was reported. Results for the association between increasing level of stress and GC were heterogeneous by smoking and socioeconomic status (p for heterogeneity = 0.02 and <0.001, respectively). In conclusion, long sleep duration (≥9 h) was associated with GC and its subtype categories. Stress linearly increased the risk of GC and was related to noncardia GC.
ObjectivesWe examined the use of low (<400 μg/day, including no use) and high folic acid supplement (FAS) dosages (≥1000 μg/day) among pregnant women in Spain, and explored factors associated with ...the use of these non-recommended dosages.DesignPopulation-based cohort study.SettingSpain.ParticipantsWe analysed data from 2332 pregnant women of the INMA study, a prospective mother-child cohort study in Spain.Main outcome measuresWe assessed usual dietary folate and the use of FAS from preconception to the 3rd month (first period) and from the 4th to the 7th month (second period), using a validated food frequency questionnaire. We used multinomial logistic regression to estimate relative risk ratios (RRRs).ResultsOver a half of the women used low dosages of FAS in the first and second period while 29% and 17% took high dosages of FAS, respectively. In the first period, tobacco smoking (RRR=1.63), alcohol intake (RRR=1.40), multiparous (RRR=1.44), unplanned pregnancy (RRR=4.20) and previous spontaneous abortion (RRR=0.58, lower use of high FAS dosages among those with previous abortions) were significantly associated with low FAS dosages. Alcohol consumption (RRR=1.42), unplanned pregnancy (RRR=2.66) and previous spontaneous abortion (RRR=0.68) were associated with high dosage use. In the second period, only tobacco smoking was significantly associated with high FAS dosage use (RRR=0.67).ConclusionsA high proportion of pregnant women did not reach the recommended dosages of FAS in periconception and a considerable proportion also used FAS dosages ≥1000 μg/day. Action should be planned by the Health Care System and health professionals to improve the appropriate periconceptional use of FAS, taking into consideration the associated factors.
: Inconsistent findings have been reported regarding the relationship between dietary iron intake and the risk of gastric cancer (GC).
: We pooled data from 11 case-control studies from the Stomach ...Cancer Pooling (StoP) Project. Total dietary iron intake was derived from food frequency questionnaires combined with national nutritional tables. We derived the odds ratios (ORs) and 95% confidence intervals (CIs) for quartiles of dietary iron through multivariable unconditional logistic regression models. Secondary analyses stratified by sex, smoking status, caloric intake, anatomical subsite and histological type were performed.
: Among 4658 cases and 12247 controls, dietary iron intake was inversely associated with GC (per quartile OR 0.88; 95% CI: 0.83-0.93). Results were similar between cardia (OR = 0.85, 95% CI = 0.77-0.94) and non-cardia GC (OR = 0.87, 95% CI = 0.81-0.94), and for diffuse (OR = 0.79, 95% CI = 0.69-0.89) and intestinal type (OR = 0.88, 95% CI = 0.79-0.98). Iron intake exerted an independent effect from that of smoking and salt intake. Additional adjustment by meat and fruit/vegetable intake did not alter the results.
: Dietary iron is inversely related to GC, with no difference by subsite or histological type. While the results should be interpreted with caution, they provide evidence against a direct effect of iron in gastric carcinogenesis.
IMPORTANCE: High-quality dietary patterns may help prevent chronic disease, but limited data exist from randomized trials about the effects of nutritional and behavioral interventions on dietary ...changes. OBJECTIVE: To assess the effect of a nutritional and physical activity education program on dietary quality. DESIGN, SETTING, AND PARTICIPANTS: Preliminary exploratory interim analysis of an ongoing randomized trial. In 23 research centers in Spain, 6874 men and women aged 55 to 75 years with metabolic syndrome and no cardiovascular disease were enrolled in the trial between September 2013 and December 2016, with final data collection in March 2019. INTERVENTIONS: Participants were randomized to an intervention group that encouraged an energy-reduced Mediterranean diet, promoted physical activity, and provided behavioral support (n = 3406) or to a control group that encouraged an energy-unrestricted Mediterranean diet (n = 3468). All participants received allotments of extra-virgin olive oil (1 L/mo) and nuts (125 g/mo) for free. MAIN OUTCOMES AND MEASURES: The primary outcome was 12-month change in adherence based on the energy-reduced Mediterranean diet (er-MedDiet) score (range, 0-17; higher scores indicate greater adherence; minimal clinically important difference, 1 point). RESULTS: Among 6874 randomized participants (mean SD age, 65.0 4.9 years; 3406 52% men), 6583 (96%) completed the 12-month follow-up and were included in the main analysis. The mean (SD) er-MedDiet score was 8.5 (2.6) at baseline and 13.2 (2.7) at 12 months in the intervention group (increase, 4.7 95% CI, 4.6-4.8) and 8.6 (2.7) at baseline and 11.1 (2.8) at 12 months in the control group (increase, 2.5 95% CI, 2.3-2.6) (between-group difference, 2.2 95% CI, 2.1-2.4; P < .001). CONCLUSIONS AND RELEVANCE: In this preliminary analysis of an ongoing trial, an intervention that encouraged an energy-reduced Mediterranean diet and physical activity, compared with advice to follow an energy-unrestricted Mediterranean diet, resulted in a significantly greater increase in diet adherence after 12 months. Further evaluation of long-term cardiovascular effects is needed. TRIAL REGISTRATION: isrctn.com Identifier: ISRCTN89898870
The consumption of ultra-processed foods (UPF) has been associated with higher all-cause and cardiovascular disease (CVD) mortality, although this association has not been sufficiently investigated ...in Mediterranean populations. We aimed to evaluate the association between UPF consumption and all-cause, CVD and cancer mortality in an adult population in Spain.
We analysed data from 1,538 participants aged 20 years and above in the Valencia Nutrition Survey in 1995. Diet was assessed at baseline using a validated food frequency questionnaire and the consumption of UPF was calculated using the NOVA system. Information on socio-demographic characteristics, lifestyles, and presence of diseases was also collected at baseline. Cause of death was ascertained during an 18-year follow-up period. We used Cox regression and competing risk models as proposed by Fine and Gray's to estimate adjusted hazard ratios (HR) and 95 % confidence intervals (95 %CI).
After 18 years of follow-up, we documented 312 deaths (36.5 % of CVD and 25.6 % of cancer). Compared with participants in the lowest tertile of UPF consumption, those in the highest tertile showed 40 % higher risk of all-cause mortality, HR 1.40 (95 %CI: 1.04–1.90), and evidence of a higher CVD mortality, HR 1.39 (95 %CI: 0.80–2.41) and of cancer mortality, HR 1.53 (95 %CI: 0.83–2.82).
This study suggests that a high UPF consumption is associated with a higher all-cause mortality in a Mediterranean population after a long follow-up period. Considering the increase in UPF consumption and their detrimental health effects on mortality, these results should be confirmed by other studies in other populations.
