Short sleep duration has been associated with added sugar intake, and both are risk factors for cardiometabolic diseases ^{(Reference Shahdadian, Boozari and Saneei1, Reference Al Khatib, Hall and Creedon2)}. The aim of this project is to analyses the relationship between added sugars (AS) intake and sleep duration in Mexican adults.

Healthy subjects (women and men: 18–50 y, BMI 18.5–39.9 kg/M2) from the Autonomous University of Sinaloa, participated in this free-living study. Sociodemographic, anthropometric, and clinical data was used for characterisation. During the 4-week study period, participants completed a 7-day actigraphy record, and four 24-h dietary recall. Sleep duration was objectively assessed using the MotionWare® software. To estimate AS intake, by using a previously developed methodology ^{(Reference Louie, Moshtaghian and Boylan3)}, the work team created a food composition table, containing updated AS content for 1706 food items. Protocol was approved by the ethics and research committee of the Faculty of Nutrition and Gastronomy (CE-FCNYG-2021-SEP-001). Data, analysed by ANOVA and ANCOVA with energy intake (kcal/d) and age (y) as covariates, are presented as mean ± SD.

Twenty one healthy subjects (13 W, 8 M) completed the study, for comparison, the sample was categorised into three groups, based on sleep duration: A) 4 to ≤5 h (n = 6); B) >5 to ≤6 h (n = 8); and C) >6 to ≤ 7 h (n = 7). Age (27.1 ± 8.2 y), BMI (25.3 ± 2.7 kg/M2), waist circumference (84.72 ± 9.38 cm), and blood pressure (SBP 110.38 ± 12.7 mmHg, and DBP 71.79 ± 5.6 mmHg) were equivalent among groups (P ≥ 0.05). Body fat was greater in group C (37.2 ± 5.3%) than in group A (22.2 ± 8.0%) (P = 0.013), and equal to group B (25.8 ± 11.0%).

Sleep analysis showed a sleep duration of 5:34 ± 0:48 h:mm (95% IC: 5:12, 5:56 h:mm), and sleep duration was greater in group C than in A and B (P = 0.000): A) 4:35 ± 0:18 h:mm; B) 5:28 ± 0:14 h:mm, and C) 6:30 ± 0:14 h:mm.

Dietary analysis showed higher intake of energy and carbohydrates in the group A (P ≥ 0.05). Data are presented as the mean of four days: Energy, kcal/d: A) 2401.1 ± 443.0, B) 2016.6 ± 749.8, and C) 1790.9 ± 348.7. Carbohydrates, g/d: A) 275.2 ± 44.5, B) 242.0 ± 74.9, and C) 202.7 ± 35.7. Added sugar (g/d) showed a tendency to a greater intake in group A) 63.8 ± 23.3; than B) 60.5 ± 35.1, and C) 51.75 ± 14.53 (P = 0.071).

All the participants were short sleepers (4 to ≤7 h), however participants with the shortest sleep duration (4 to ≤5 h) showed greater intake of energy and carbohydrates, but a deeper analyses and a bigger sample is needed before conclude if added sugar intake could have any interaction with sleep duration.
