Abstract

BACKGROUND

Despite growth in the number of cruises worldwide, evidence about diarrhea experienced by cruise ship passengers remains sparse. We investigated rates of diarrhea and related factors among passengers on world cruises departing from Japan.

METHODS

Targeting passengers on five world cruises (n = 4180) from 2012 to 2013 (85-103 travel days), we calculated rates of health seeking behavior for diarrhea by sex, age group, and number of roommates for each cruise. We estimated rate ratios and 95% confidence intervals, using the group aged 20-39 years, women, and 2-4 roommates as referent categories.

RESULTS

We found 5.04-6.00 cases per 10,000 person-days in the five cruises, with an elevated number after calling at ports. Older passengers (>60 years) and passengers with fewer roommates had an elevated risk of health seeking behavior for diarrhea, although passengers aged <20 years had an elevated risk on one cruise. After controlling for covariates (including cruise), significant associations remained for passengers aged >60 years and without roommates.

CONCLUSIONS

Older passengers and passengers with fewer roommates may be more likely to seek medical treatment for diarrhea during travel on a world cruise, and should take preventive measures.

摘要

背景

尽管全球游轮数量不断增加，但有关游轮乘客腹泻的证据仍然很少。我们调查了从日本出发的环球游轮乘客腹泻的发生率及相关因素。

方法

我们针对 2012 年至 2013 年间（85-103 个旅行日）的五艘环球游轮（n=4180 名）乘客进行了研究，按性别、年龄组和每个游轮的室友人数计算了腹泻求医行为的发生率。我们使用年龄在 20-39 岁、女性和 2-4 名室友的群体作为参照类别，估计了率比值和 95%置信区间。

结果

在五艘游轮中，每 10000 人日腹泻病例为 5.04-6.00 例，在停靠港口后病例数增加。年龄较大的乘客（>60 岁）和室友较少的乘客腹泻求医行为的风险增加，但在一艘游轮上，年龄<20 岁的乘客腹泻求医行为的风险增加。在控制了协变量（包括游轮）后，对于年龄>60 岁和没有室友的乘客，仍存在显著关联。
