iron infusion (preferably with ferric gluconate or sucrose) may
be needed for patients with severe intolerance to oral iron or
refractory deficiency due to severe iron malabsorption.
Baseline and postoperative evaluation for vitamin B12 defi-
ciency is recommended in all bariatric surgery and annually
in those with procedures that exclude the lower part of
the stomach (e.g., LSG, RYGB). Oral supplementation with
crystalline vitamin B12 at a dosage of 1,000
μ
g daily or
more may be used to maintain normal vitamin B12 levels.

tation, 1,000

indicated if B12 sufficiency cannot be maintained using oral or
intranasal routes.
In patients who have undergone RYGB, BPD, or BPD/DS,
treatment with oral calcium citrate and vitamin D (ergocalcif-
erol [vitamin D2] or cholecalciferol [vitaminD3]), is indicated to
prevent or minimize secondary hyperparathyroidism without
inducing frank hypercalciuria. 1,200

1,500 mg of elemental
calcium (in diet and as citrated supplement in divided doses),
at least 3,000 international units of vitamin D (titrated to

of severe vitamin D malabsorption, oral doses of vitamin D2
orD3mayneedtobeashighas50,000units1to3timesweeklyto
daily, and more recalcitrant cases may require concurrent oral
administration of calcitriol (1,25-dihydroxyvitamin D). Amajor
clinical concern is the relationship between vitamin D defi-
ciencyandthedevelopmentofmetabolicbonediseases,suchas
osteoporosis or osteomalacia; metabolic bone diseases may
explain the increased risk of hip fracture in patients after RYGB.

In 2015, the Diabetes Association in Taiwan published its
clinical practice guidelines for diabetes care. There are 3
different screening methods for diabetes in asymptomatic
subjects suggested by the guideline. The first one is based on
the service by the National Health Insurance in Taiwan. In
adults aged 40
–
64 years, screening for diabetes every 3 years
should be considered. For adults aged 65 or over, annual
screening for diabetes is recommended. The second one is
based on Taiwan Diabetes Risk Scores, which is a risk assess-
ment calculator, to estimate the risk for undiagnosed diabetes.
For subjects with very high risk for undiagnosed diabetes,
annual screening is recommended. For subjects with high or
moderate risk for diabetes, screening every 3 years is recom-
mended. The third one is based on risk factors of diabetes.
Subjects who have impaired fasting glucose, impaired glucose
tolerance, or HbA1c 5.7
–
6.4% are suggested to be tested
annually. For subjects with two or more risk factors, screening
is recommended every 3 years. The guideline also suggests a
screening algorithmto confirmthe diagnosis of diabetes and to
determine the needof oral glucose tolerance test, basedondata
of fasting plasma glucose and hemoglobin A1c. The diagnostic
criteria for diabetes and for the category of increased risk for
diabetes (pre-diabetes) remain the same as in the previous
version. For the diagnosis of gestational diabetes mellitus
(GDM), both one-step strategy and two-step strategy are
recommended. The one-step strategy increases prevalence of
GDM, but results in an improvement in maternal and fetal
outcome and is cost-effective in Taiwan. Besides, the DAROC
has also createdan interactivewebsite for theusersto learnand
get familiar with the screening of diabetes, the diagnosis of
diabetes, and the treatment algorithm of the guideline.

Non-communicable chronic diseases have become the leading
causes of mortality and disease burden worldwide. As the
most populous country, the rapid increase in morbidity and
mortality from non-communicable diseases in China con-
tributed to the pandemic, including diabetes. The prevalence
of diabetes has increased significantly in recent decades and
is now reaching epidemic proportions in China. The preva-
lence of diabetes was less than 1% in the Chinese population in
1980. In subsequent national surveys conducted in 1994 and
2000
–
2001, the prevalence of diabetes was 2.5% and 5.5%,
respectively, and 9.7% in 2007. Although different sampling
methods, screening procedures and diagnostic criteria were
used, these data document a rapid increase in diabetes in the
Chinese population. In 2010, wemeasured HbA1c, FPG, and 2-h
PG in a large and nationally representative sample of 98,658
adults aged 18 years or older to estimate the prevalence and
control of diabetes based on the 2010 ADA criteria in the
general Chinese population. The estimated prevalence of
diabetes and pre-diabetes in a representative sample of
Chinese adults was 11.6% and 50.1%, respectively. Projections
based on sample weighting suggest this may represent up to
113.9 million and 493.4 million adults, respectively. These
findings indicate the importance of diabetes as a public health
problem in China. The estimated percentage of ideal cardio-
vascular health was 0.2% in the general adult population in
China (0.1% in men and 0.4% in women). We also reported for
the first time, compared with the general population in China,
most cardiometabolic risk factors were less prevalent in
migrant workers. However, overweight, obesity and central
obesity were more prevalent in male migrant workers than
among men in the general population. Cardiometabolic risk
profiles for migrant workers are not optimal and effective
national interventions that can reach this special population
are needed.

Background:
The prevalence of childhood obesity has
increased from 13% in 1986, 26.8% in 2001 and now 32.3% in
2010. The prevalence of impaired fasting glucose in Taiwanese
adolescents is 22%. The rate of newly identified diabetes was
9.0 per 100,000 for boys and 15.3 per 100,000 for girls. Of 253
children with newly diagnosed diabetes, 24 (9.5%) had type 1
DM, 137 (54.2%) had type 2 DM, and 22 (8.7%) had secondary
diabetes. Childhood obesity is themost contributing risk factor
leading to type 2 diabetes, and also metabolic syndrome. We
aim to explore the relationship amongst socio-demographic,
