To investigate the relationship between eating frequency and specific adiposity markers in a potentially high-risk and understudied population of Hispanic college freshmen.
This study included 92 Hispanic college freshmen (18-19 y). The following cross-sectional data were collected: height, weight, waist circumference, body mass index (BMI), dietary intake, body composition, physical activity, hepatic fat, visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT).
Infrequent eaters ate 44% less often (2.5 ± 0.2 vs. 4.5 ± 0.8, ≤ 0.01) and consumed 27% more calories per EO ( ≤ 0.01), while consuming 21% less kcals per day ( ≤ 0.01) compared to frequent eaters. Infrequent eaters had 8% higher BMIs (24.8 ± 4.4 vs. 22.9 ± 3.2 kg/m) ( = 0.02) 60% higher BMI z-scores (0.5 ± 1.0 vs. 0.2 ± 1.0, = 0.03) 21% higher VAT (298.3 ± 153.8 vs. 236.8 ± 78.2 ml, = 0.03), 26% higher SAT (1150.1 ± 765.4 vs. 855.6 ± 494.6 ml, = 0.03), and 8% higher total body fat (27.6 ± 10.8 vs. 25.3 ± 8.8%, = 0.04) compared to frequent eaters while showing no significant difference in physical activity. These findings seem to be driven by females more than males.
These findings suggest that infrequent eating is related to increased adiposity in Hispanic college freshmen, despite a decreased daily energy intake and no significant differences in physical activity. Yet, more research is needed to understand the underlying mechanisms of these findings, as well as investigate any potential causal relationship between eating frequency and adiposity in Hispanic youth.
研究西班牙裔大学新生这一潜在高危且研究不足的人群中进食频率与特定肥胖标志物之间的关系。
本研究纳入了92名西班牙裔大学新生（18 - 19岁）。收集了以下横断面数据：身高、体重、腰围、体重指数（BMI）、饮食摄入、身体成分、身体活动、肝脏脂肪、内脏脂肪组织（VAT）和皮下脂肪组织（SAT）。
与频繁进食者相比，不频繁进食者进食频率低44%（2.5 ± 0.2次/天对4.5 ± 0.8次/天，P≤0.01），每次进食摄入的热量多27%（P≤0.01），但每天摄入的千卡热量少21%（P≤0.01）。不频繁进食者的BMI高8%（24.8 ± 4.4对22.9 ± 3.2 kg/m²）（P = 0.02），BMI z评分高60%（0.5 ± 1.0对0.2 ± 1.0，P = 0.03），VAT高21%（298.3 ± 153.8对236.8 ± 78.2 ml，P = 0.03），SAT高26%（1150.1 ± 765.4对855.6 ± 494.6 ml，P = 0.03），全身脂肪高8%（27.6 ± 10.8对25.3 ± 8.8%，P = 0.04），而身体活动无显著差异。这些发现似乎在女性中比在男性中更明显。
这些发现表明，在西班牙裔大学新生中，尽管每日能量摄入减少且身体活动无显著差异，但不频繁进食与肥胖增加有关。然而，需要更多研究来了解这些发现的潜在机制，以及调查西班牙裔青少年进食频率与肥胖之间的任何潜在因果关系。
