Background: Hispanics in the United Statues are disproportionately affected by Alzheimer’s disease and related dementias. Little is known about the impact of acculturation on cognitive performance. Objective: This study examined the association between acculturation and cognitive performance among older Hispanics. Methods: We analyzed cross-sectional data of 616 Hispanic participants in the National Health and Nutrition Examination Survey (NHANES) 2011–2014 [average age = 67.15 years, %Female = 51.46, %less than high-school graduate = 52.60]. Cognitive performance was measured by two neuropsychological tests: Animal Fluency Test (AFT) and Digit Symbol Substitution Test (DSST). We used two single-item proxy measures to quantify acculturation: nativity status (non-US-born residing <  15 years in the US (low acculturation), non-US-born residing ≥15 years in the US, and US-born (high acculturation)); and language acculturation (only/mostly Spanish (low acculturation), Spanish and English, only/mostly English (high acculturation)). We used adjusted linear regression to evaluate associations between acculturation and cognitive performance. Results: Results indicated poorer cognitive performance among the low-acculturated groups for both nativity and linguistic measures. Participants who were non-US-born living ≥15 years (p = 0.02) and speaking only/mostly Spanish or Spanish and English (p = 0.01 and 0.006 respectively) had significantly lower AFT scores compared to US-born and only/mostly English-speaking groups. Participants who were non-US-born living <  15 years (p <  0.0001) or non-US-born living ≥15 years (p <  0.0001) and speaking only/mostly Spanish (p = 0.0008) scored lower on the DSST than the US-born and only/mostly English-speaking participants. Conclusion: In summary, low acculturation is associated with poorer cognitive performance among older Hispanics. Acculturation might be an important attribute to help understand cognitive decline and dementias among Hispanics.

Objectives To evaluate the moderating effect of feeding styles on the association between satiety responsiveness and child BMI z-scores in children aged 3-to-5 in Santiago, Chile. Methods Participants were recruited from childcare centers serving low- and middle-income families in 2017 and 2018. During a face-to-face individual interview, the Caregiver Feedings styles Questionnaire and food responsiveness subscale of the Child Eating Behavior Questionnaire were applied to parents. Weight and height were obtained for children and caregivers. Multiple linear regressions were conducted to test the moderating effect of feeding styles on the relationship between satiety responsiveness and child BMI z-scores. Results 92.5% of caregivers were mothers, the parent BMI was 29.2 (SD = 5.7). No feeding style moderated the association between satiety responsiveness and BMI z-score Satiety responsiveness had a significant main effect on child BMI z score. None of the feeding styles was significantly associated with child BMI z-score. Only satiety responsiveness was significantly associated with child BMI z score (B = –.32, P &lt; 0.05) after controlling for parent BMI (B = .047, P &lt; .05). This model accounted for 12% of the variance of the child BMI z-score. 1.1% of the children were underweight, 22.4% normal, 37.9% overweight and 38.5% obese Conclusions Parent perceptions of higher satiety responsiveness suggests an association with lower child BMI z-scores. This study suggests that how children respond to food may play an important role in explaining child weight status. than the parent's or caregiver style of feeding in determining a child's weight status. Further research is required to discard interaction effects between appetite traits and feeding styles to explain child weight status.

A B S T R A C TIndustrial waste discharge has increased the hazard of water pollution. The total hydrocarbon content and bioaccumulation of heavy metals in Sarotherodon melanotheron at Atlas cove area and at Okobaba end of Lagoon Lagos were assessed between November, 2014 and January, 2015. The physicochemical parameters were determined according to APHA-AWWA-WEF and heavy metals in the fish species were determined using Atomic Absorption Spectrometer. The total hydrocarbon content (THC) in the fish samples were analysed by using Soxhlet extraction gravimetric methods. The heavy metal values evaluated are Fe, Cr, Pb, Ni and Cu. The concentration of Iron (Fe) in Sarotherodon melanotheron was 72.72 ± 125.95mg/kg, Chromium (Cr)-10.29 ± 4.61mg/kg; Lead (Pb)-1.08 ± 0.23mg/kg; Nickel (Ni)-0.39 ± 0.26mg/kg; and Copper (Cu)-0.20 ± 0.26mg/kg at Atlas cove area while at Okobaba the concentration were;Fe-115.98±87,Cr-5.25±1.02,Pb-2.04±1.50,Ni-0.78±0.08,and Cu is 0.36±0.15mg/kg. The levels of accumulation of all the heavy metals in Sarotherodon melanotheron were above the WHO permissible limits. The concentration of n-alkanes in Sarotherodon melanotheron at Atlas cove was 164.69 ± 97.04µg/g, polycyclic aromatic hydrocarbon (PAH) was 73.58 ± 72.48µg/g, and total petroleum hydrocarbon was 526.67 ± 214.34µg/g. The average intake of polycyclic aromatic hydrocarbon through fish consumption at Atlas cove area was estimated to be 5039.94 ± 49.2mg/kg; body weight/day. The mean concentration of nalkanes hydrocarbon in Sarotherodon melanotheron at Okobaba was 152.62±54.11µg/g, the Polycyclic Aromatic Hydrocarbon (PAH) was 74.4±50.30 µg/g.The carcinogenic high molecular weight polycyclic aromatic hydrocarbons (HMW-PAH) were of higher concentrations than the lower molecular weight polycyclic aromatic hydrocarbon (LMW-PAH). Therefore, Atlas cove area is more exposed to carcinogenic health risks associated with the consumption of the studied fish than Okobaba end of Lagos Lagoon. This indicates significant carcinogenic health risks associated with the consumption of black jaw Tilapia fish caught from the study areas.
